Heather Tienson-Tseng BCHM463 Expecting an A Anonymous 11/02/2023	Honestly I don't understand why everyone gave her a bad review. Yeah her class was hard, but it's a hard class win general. Everyone just hates on a teacher with a hard class. Getting an A is definitely manageable if u put the time in and she is always available if you need help.
Heather Tienson-Tseng CHEM131 Expecting an A Anonymous 08/23/2023	I took her freshman connection CHEM131 course in Fall 2022. The structure of her course consisted of lectures with clicker questions, discussion sections with a graded group worksheet, homework, and exams. I felt that the way the class was set up was unstable and messy. Half of the grades were in Canvas while the other half were in Gradescope and Achieve (the textbook/homework software), so you had to calculate your own grade which wasn't even accurate half the time. Dr. Tseng's lecturing style was going through slides and explaining/working out problems by drawing on the slides. While it is helpful to see the problems done in front of you, her explanations could be hard to follow and ineffective at times. The exam averages were low, and it was hard to expect what would be on the exam because of all the different sources of course content. Because of this she gave a generous curve at the end of the semester. All this being said, Dr. Tseng is a kind person. I would definitely recommend going in for office hours if you are having trouble. I also appreciated that she recorded the lectures, so I didn't miss anything if I couldn't make it to class. I would recommend taking a different professor if you are able, but just know it's not the end of the world if you end up with Dr. Tseng.
Heather Tienson-Tseng BCHM463 Expecting an A- Anonymous 05/22/2023	I rlly think Dr. T has an over-exaggerated bad reputation. She records all of her lectures and posts them for students to rewatch (which is rlly helpful for a class like this) and basically drops a quiz/homework by providing buffer points in those grading categories. Compared to other professors, I feel like her class is a lot easier to earn an A in. Her lecturing style can get quite boring as she fills her time speaking with filler words and takes a while to get to the main point. I actually learned a lot from this class and really enjoyed it compared to organic chemistry. I would honestly take her again if I had to do it all over again.
Heather Tienson-Tseng BCHM463 Expecting an A Anonymous 05/21/2023	as others have mentioned, tseng is simply a horrible lecturer. she's knowledgeable (to an extent), but i'll leave the detail to the other reviewers from spring 2023. she is actually not going to be here next year so this review may not be too up to date if she does ever return. simply put, i was intending to take dixon for 463 but needed to keep my 4-year plan on schedule. loved orgo 1 and 2 with dixon, loved chemistry from there on. tseng ruined it completely. good luck to anyone who has to take this with her. the course itself is not easy already; you're jumping from topic to topic with less connection than in orgo, where the central theme is "reactions, synthesis, stability," etc. thus you really NEED a professor who stays on pace, is efficient, and is willing to say "come see me after class or at OH" rather than stand in lecture for 10 minutes trying to answer a question.
Heather Tienson-Tseng BCHM463 Expecting an A- Anonymous 05/15/2023	Dr. Tseng is certainly not the best professor I've ever had, but I don't think she's as bad as her reviews make it sound. BCHM463 moves at a breakneck pace, but that's not exactly surprising given that the class is packing two semesters worth of information into one course. I probably would not recommend this professor for an entry level chemistry course; that's probably where her abysmal score comes from. Her exams are challenging but ultimately fair, and she's very open to regrades. The rubrics can be a bit picky. Your scores on her exams will probably be lower than you want them to be, but half of the points in the class come from clicker points, homeworks, and quizzes, all of which have built in extra points making it easy to get 100% in those categories and overall buoying your grade. She can come across a bit intense in class, but going to her office hours is extremely helpful and she's nice and patient in those. Make sure you make use of the practice problems she uploads! They're all former exam questions which makes for great study material.
Heather Tienson-Tseng CHEM131 Expecting a B- Anonymous 05/09/2023	I wish I could give 0 stars. This class traumatized me. I love science classes and loved chem in high school, but I'm NOT joking when I say that this class killed something inside of me. Dr. Tseng cannot teach this class and I'm surprised that she is allowed to. I'm not sure if she should just be teaching something more advanced or not but it definitely shouldn't be gen chem. Her handwriting is awful so it's hard to write down correct notes as she's solving, there is SO MUCH HOMEWORK, and the exams are literally the hardest exams I have ever taken. Practice problems, homework, study guides, videos, and even an expensive tutor couldn't save me. I failed every single exam, and so did the majority of the class, and she had to curve the grades so much to accommodate for it. Think about it. I got an F on 3 midterms and the final and still ended with a B. Impossible, and it only shows how poorly everyone did with her teaching. FIND A DIFFERENT PROFESSOR FOR THIS COURSE IT IS NOT WORTH THE MENTAL BREAKDOWNS.
Heather Tienson-Tseng BCHM463 Expecting an A Anonymous 04/28/2023	As the other reviews have mentioned, Dr. Tseng is not the best professor. Her slides often contain very little information and her lectures cover very superficial material. Furthermore, we spend about 1/3 of class every lecture on clicker questions. What this means is that we move extremely slowly through the content of this class. Keep in mind this is BCHM463 which is essentially a condensation of BCHM461+BCHM462. While the slower pace may seem like a good thing, the issue is that many individuals who take this class often do so in preparation for future classes or the MCAT. I can say for sure that Dr. Tseng's class does not prepare you well for these things. This is made worse by Dr. Tseng's grading. Most of Dr. Tseng's homeworks and exams have almost arbitrary sentence limits which prevent you from fully explaining your thinking. Exams often ask for 4-5 different points, but she asks students to condense this information within 2 sentences. This is far from necessary and is not an accurate reflection of a student's "ability to communicate" as Dr. Tseng puts it. Rather, it only makes it more difficult for students to showcase their knowledge of a topic. The rubrics are also extremely specific making exams and homework more of a guessing game of what Dr. Tseng wants you to say within the 1-3 sentences you are allowed rather than a showcase of knowledge. Ultimately, she does provide a lot of study material which can guide your thinking and she does emphasize a solid foundation of theory rather than rote memorization which is why she isn't 1-2 stars, but I would recommend choosing another professor before her!
Heather Tienson-Tseng CHEM131 Expecting a B Anonymous 04/04/2023	So I must admit Tienson is not the best professor. Her handwriting is close to unreadable, and she gets flustered easily when asked questions during lecture. Also she wasn’t the best at explaining concepts and tends to over-explain or overcomplicate things in lecture, and often looses her train of thought. HOWEVER, she does seem to genuinely want to see her students succeed and although I never went to her office hours (don’t be like me, you should go) I was told that she was kind and more helpful during them. Also, I found the achieve homeworks helpful and she usually put out a TON of extra practice problems before the exam, which were always useful. The clicker questions we did in class also counted as extra credit so that was nice, even though we didn’t end up doing as many as she said we would in the beginning. I thought her exams and curves were reasonable and I honestly did better than I thought I would in this class. The only thing I really did not like were the group quizzes and exams, as I didn’t really find them very helpful and it was sometimes a little difficult to interact and coordinate with my group-mates as a disabled student, however I can see how they could be helpful to other students. Overall she wasn’t the best professor however she gave us opportunities to do well without being overly stressed, and tried to make the class not as test-heavy which I appreciated as chemistry is pretty difficult for me.
Heather Tienson-Tseng BCHM463 Expecting an A Anonymous 01/19/2023	I did very well in this class, however, she is a horrible professor and enjoys watching her students fail. If you have any chance to get another professor, do it. I spent 8 hours a day studying for this class, every day, for 2 weeks prior to the exams just to get 75% on them, while most of my friends got 50%. She refused to release the averages and the curve was very small. I would go to office hours and she was very rude and condescending. You need to write every single thing she says in your notes, because it will all be on the exam. This is very difficult because she goes through one whole unit a day. Additionally, she refuses to give any partial credit on exams/HW even if you clearly display that you understand the information. She takes off points if you don't write it word for word how it is on the answer key. The exams are very long, like 6 pages in one hour, requiring very detailed and lengthy responses in a very small amount of time. She has in person clicker questions, so attendance is essentially mandatory, she doesnt post HW until Tuesday night, due Thursday night, but the majority of the info for the HW isn't taught until Thursday, and the HW is very difficult and time consuming. She has in-person quizzes in which you have 5 minutes for the entire quiz, in which you have to memorize and draw every amino acid, or the TCA cycle, or carbon tracing etc. However, she does provide you with a lot of study material which is very useful and is the only way you have a chance of passing the class. She also puts a sentence limit on exam questions ("2 SENTENCES MAX") yet the answer key requires 6 different pieces of info for full credit. It is so stupid. If you'll put in the work (6 hours a day), you will be fine and enjoy it because its actually interesting, if not, you're fucked so don't take her.
Heather Tienson-Tseng CHEM131 Expecting a B Anonymous 12/15/2022	Try to take a different professor if you can. I ended up taking her and truly was just not happy with her teaching, let alone her handwriting. She will help you if you ask questions in person to her, but she does not teach super great. You need to read the textbook if you want to have some clue of what is going on.
Heather Tienson-Tseng CHEM131 Expecting a B Anonymous 12/15/2022	This professor doesnt even know chemistry. She doesn't even know what shes talking about half of the time. She goes over some powerpoint and expects us to actually understand what shes saying and doing. She has assignments on Achieve which you basically have to figure out yourself since she doesn't even go over any of that material properly. She does curve the class though. If you actually want to learn anything don't take this class. If you end up with her, good luck. Dont lose points on things like discussion worksheets, achieve homeworks/preclass assignments, and clicker questions. Someone take away her doctorate degree ASAP !!
Heather Tienson-Tseng BCHM463 Expecting an A Anonymous 11/15/2022	Clearly not fit to be a lecturer. Does not explain concepts well, messy handwriting, unclear expectations, frequently makes mistakes on answer keys and is inconsistent with grading. She has sentence limits on exams and fails to realize that 2 sentence explanations are not suitable for some topics in biochemistry. However, she gives a lot of practice problems, which I will give her credit for. If you feel like you would excel in a class in which no one knows what they are talking about, not even the lecturer herself, then this would be the right class for you!
Heather Tienson-Tseng CHEM131 Expecting an A- Anonymous 11/13/2022	I took AP Chem in high school so this made it easier to get through the class but she is just not good. She doesn't teach anything and she makes you read the textbook if you want to get any knowledge at all. She has awful handwriting and a pretty bad attitude sometimes. She doesn't teach anything and even some of her problems had the wrong answer. Do not reccomend.
Heather Tienson-Tseng CHEM131 Expecting an A Anonymous 05/05/2022	Took AP Chem in high school, so I was not expecting to put a ton of effort into this class. God was I wrong. Dr. Tseng was not a good lecturer, although I was usually able to follow up on the content based on prior knowledge. The Top Hat homeworks were helpful in terms of what to expect on exams, but that was pretty much the only material that helped. She had practice exams that were nothing like the actual exams, so eventually I stopped even doing them. Her handwriting was also horrible, so the exam keys and other keys were impossible to read and frequently had mistakes. Her problems on exams were also really hard for Gen Chem 1- harder than anything I had seen in AP Chem (which combines Gen Chem 1 and some of Gen Chem 2). This was reflected by the averages on exams- which she wouldn't even tell us because they were so low. All I know is there was never an average above a 50- which included the final. There was definitely a curve as I never got an A on an exam and still ended with an A, but when I took the class I had no clue what my grade was till final grades were released. To add, discussions were also graded, so keep that in mind if you like optional discussions. To add to this, as if it could not have gotten worse, exams were scheduled at the worst times possible. Had this class at 8 AM and one of our exams was the day after Halloween, with the other the day after Thanksgiving. Timing literally could not have been worse. Only good thing that came out of this class was the curve and that OChem genuinely feels easier because Tsengs' tests were just that hard. Take her as a last resort.
Heather Tienson-Tseng CHEM131 Expecting a B+ Anonymous 04/26/2022	So terrible. Smartest person I know is me, and I could barely pass. DO NOT TAKE THIS CLASS. Even if you have to take an extra semester of classes just to avoid this professor - do it. DO NOT TAKE THIS GOD AWFUL PROFESSOR. Whoever allowed her to teach should be sent to the deepest pits of hell. :)
Heather Tienson-Tseng BCHM463 Expecting an A Anonymous 03/28/2022	ima keep it brief, tseng is an okay professor -- she isnt the best lecturer so i stopped going to lecture, instead i speedrun her lecture recordings just to get a general idea of the concepts. she posts slides that are relatively easy to follow. she gives quizzes every now and then which you could just study for quickly with a quizlet (free points) and homeworks take some time but just refer to notes and see if there is overlap with her posted practice problems. her exams are very demanding in detail for your answers, she wants every essential piece of reasoning and justification, but the key to doing well in her class is grinding tf out of practice problems -- she posts a f*ck ton of practice which are all old exam problems, chances are when you're taking your actual exam some of those same problems will come up with a slight change in detail. main takeaway: you can not invest a lot of time in this class and still manage to do well, just be strategic and find what works.
Heather Tienson-Tseng CHEM131 Expecting an A- Anonymous 03/25/2022	Mid. I took this chemistry class last fall, the questions are some of the most improperly worded things I have ever seen. Her handwriting is that of a child.
Heather Tienson-Tseng BCHM463 Anonymous 03/11/2022	Extremely heavy on memorization. Does not allow any sort of note sheet/reference guide during exams and quizzes. Asks us to memorize numerous structures with nearly indistinguishable nomenclature and also takes points for not copying desired answers rote. Would have been infinitely better with some sort of reference sheet on timed examinations. Subject matter is not hard at all, although the copious amount of information that must be memorized is quiet a feat.
Heather Tienson-Tseng CHEM131 Expecting a C+ Anonymous 02/16/2022	I actually cannot think of a single person that consistently passed the exams. The whole semester I had no idea what my grade was. Also, the material on the discussion worksheets, the homework, the lectures, and the exams was all different so just when you thought you knew what you were doing, you didn't. I thought I could do okay despite her terrible UCLA reviews. I was wrong. Please just listen to the reviews and DO NOT TAKE THE CLASS if you are applying to any sort of schooling after undergrad.
Heather Tienson-Tseng CHEM131 Expecting an A- Anonymous 12/23/2021	Her midterms are unnecessary hard. I believe the test average was below 50. I don't think she's a good lecturer. The final midterm on the first day right after the break was not it man. But I think her grading scale is pretty generous. If you did great AP Chemistry, this class would be ok for you.
Heather Tienson-Tseng CHEM131 Anonymous 12/21/2021	To put it quite simply: Tseng is a terrible professor. Her lack of compassion towards students along with her inability to teach makes her class ridiculously hard to pass. Her lectures are incomprehensible and her method as to solving the problems is more confusing and complicated than it needs to be. On top of that, she doesn’t spend too much time on practice problems in class, during the times she did, she either spent too long on a simple problem or breezed through a hard one. Homework and reading assignments were posted on tophat and they were definitely harder than what we learned in class. The practice problems for exams were also posted on tophat and they were misleading in the sense that they were nothing like the real exams. Her grades were also all over the place: some were posted on Tophat, some on Gradescope and some on Elms. It is impossible to calculate percentages in her class and you will never know what you finally get till after she posts the final exam. Throughout the semester, she kept talking about some imaginary curve but never posted it. Very difficult when you don’t know how well you’re doing and then it’s too late to drop the class. Tseng assigned “Exam Wrap-ups” for extra credit, essentially giving us an opportunity to tell her what she can improve on in her teaching and yet, she did nothing to improve the class and blamed students for the low exam scores. Two of her exams were after major holidays (Halloween and Thanksgiving) which was very stressful since she also posted homework and reading assignments to do during the break. Even some of my friends who took AP Chemistry in high school had a hard time in her class. You’re better off either self teaching or taking a different professor entirely. 0/5 stars if I could. Send her back to UCLA asap.
Heather Tienson-Tseng CHEM131 Expecting a B- Anonymous 12/21/2021	It is chemistry so expect it to be hard. When I first walked into class I walked with low expectations for the teacher. All of the chemistry teachers in my life could not teach chemistry very well. So when this teacher would speed by topics and not explain things very well I wasn't surprised. Everything everyone is saying in these comments are true. I just recommend walking in with low expectations.
Heather Tienson-Tseng CHEM131 Expecting a D Anonymous 12/20/2021	This is the absolute worst professor I have had yet if you are registering for courses please stay away. On the first exam she said she doesn't believe in giving out the class average which is something I don't like but it's not a huge deal. After the exam she sent out an email saying how disappointed she is in the student because the average was below a 50%. Nothing since that exam changed with both other mid terms being equally as difficult. For the finial she said it would be the easiest yet, short, and similar to the practice test she gave out to study. This finial exam was the most ridiculous exam I have taken, questions unlike anything that we have seen before. She couldn't care less about her students and won't let you see your grades until the very last week of the semester. STAY AWAY!!!!
Heather Tienson-Tseng CHEM131S Expecting a B Anonymous 12/16/2021	Overall, she is not a good teacher. During lectures, she is all over the place. She reads straight off the slides and her thoughts are so scrambled that it is hard to follow. Right when you feel like you are getting the material, she assigns extremely hard homework questions that make no sense. Her exams are incredibly hard, although she does change grade ranges which is the only thing I appreciate from her. She does not put grades on Canvas, so we have to manually calculate our final grade. Would it be so hard to use the college-wide database that keeps track of our grades? Also, I don't know if this was specific to this semester, but all of our midterm grades were on days where you would not want it to be on. November 1st - the day after Halloween and November 29 - the day after we come back from Thanksgiving Break. I literally blame her for ruining my Halloween and Thanksgiving Break. All I wanted to do was spend time with my friends and family, but I had to study for a test that I knew I won't do good on cause she is impossible. Please take another teacher if you can.
Heather Tienson-Tseng CHEM131S Expecting an A Anonymous 12/15/2021	Overall a pretty bad teacher. Bad at lecturing, reads right off the slides, and takes FOREVER to answer questions. Honestly it might be more useful to just watch youtube videos and attend discussions. All the exams had a super low average, and the practice exams don't really help much with the actual midterm. The weekly assignments are easy and the curve is super generous, so if you put in some effort or even get lucky on the exams you can manage an A.
Heather Tienson-Tseng CHEM131 Anonymous 12/13/2021	I genuinely do not know how this professor is teaching this course at UMD as she had never taught CHEM131 in her past. She was so ineffective in teaching the course content during lectures that I found myself watching other professors' lecture videos to try and teach myself the content. During lectures, she seemed to be teaching the content to herself as she went along. She also failed to ask students questions during the lecture. I remember a student asking a simple question in solving some sort of conversion and she responded with "I'll have to take you up on that later", leaving the student confused. On top of it all, her exams were ridiculously hard. The practice problems or practice exams did not match up whatsoever. I wish she made it more clear that she wants to see her students succeed, but she really isn't a pleasant person. She also does not input grades into ELMS. So, this entire semester I have felt that I am going in blind. Who knows what kind of curve she is going to give since her exam averages were maybe 50% at the highest. I wish I could have learned chemistry more effectively in this course because as of now, I learned so much more in my high school AP chemistry class than this one. (for anyone even thinking about taking Dr. Tseng please make sure you have taken AP Chem first, or you're screwed) Dr.Tseng seems to assume that most of her students understand the basics and don't need much explanation or demonstration of practice problems. This was an awful course experience.
Heather Tienson-Tseng CHEM131 Expecting a B- Anonymous 12/13/2021	After the majority of the class failed an exam (mind you, this test was given at 8 am the day we returned from Thanksgiving break) she said that she can only do her job and that we needed to "start doing our job". She usually seems so nice, but this sums up how she is a lecturer; she's unable to see anything from the student's perspective. I wouldn't say "don't take this class" though. Is it stressful? Yes. But I will say that it's supposed to be heavily curved. Granted you won't know your grade until the very end (she doesn't post all assignments in one place), but still, a curve is a curve.
Heather Tienson-Tseng CHEM131 Expecting a D+ Anonymous 12/11/2021	She does not explain anything because she often rushes through difficult concepts and doesn't write in a legible manner. Half of the time she gets the question wrong herself. It seems like she does not know the content during lectures, she simply reads off of her slides which are 95% from the tophat homework and she has an attitude in class. She is surprised when her exam averages are below 50. She also then continues to blame you for not doing as well as she expected which is very discouraging in this class when you study as hard as you can and still end up failing the exams. SAVE YOURSELF !!!
Heather Tienson-Tseng CHEM131 Anonymous 12/11/2021	Worst professor I have had at umd so far. Her lectures are pointless because she barely reviews the reading and questions that you do on your own and any practice questions are extremely simple compared to anything done on tests. Also, whenever someone asks a question in class, she pauses to think way too long, which is concerning since you're supposed to be an expert in this, and gives really unhelpful answers. You're better off making study groups rather than going to her awful and boring lectures. Her grading is also terrible. If 0 stars was an option I would've chosen that, 1 star is generous. She doesn't even seem like she knows what she's talking about and just reads off of her slides and still occasionally messes up. I would do a better job teaching AND do so in discussion since no one understands her teaching. I honestly feel bad for the students who try so hard and are still struggling because of her incompetence.
Heather Tienson-Tseng CHEM131 Anonymous 12/09/2021	I have never ever experienced such a bad teacher before in my life. She has definitely set the standard for worst professor ever in existence. Her lectures cover simple problems and are somewhat ok, but her exams are something else entirely. For our exam 1, the average was below a 50% (most people flunked it) and there was not enough time to complete it. For exam 2, results were better. But then exam 3 was by far the worst. Not only are you tested on material significantly harder than in lecture and TopHat, you are tested on your English deciphering skills. I have have never seen such horrid wording. Her wording makes the question 200x harder as you waste precious time on wondering what exactly she is asking. For exam 3, the average is definitely going to be in the 15%-30% range. Oh yeah and she put exam 2 the day after Thanksgiving and made me miss a highly anticipated trip I was going on with my friends. She gets high off of the suffering of students. UCLA, please take her back.
Heather Tienson-Tseng CHEM131 Anonymous 12/09/2021	she seems like a nice person but is a bad professor. can never answer questions in class, you don't know your grade for like the whole semester because of her grading system, her handwriting is really bad so it's hard to take notes in class. don't recommend if you actual want to know and understand what you're learning and doing.
Heather Tienson-Tseng Anonymous 12/08/2021	Scheduled exams after holidays at 8am on Monday which she knew students would have to choose to either study or enjoy time with family and friends. Does not do a good job answering questions and isn't confident when she is answering questions. There are not good options when it comes to Chem professors, grade wise she might be the easiest.
Heather Tienson-Tseng CHEM131 Anonymous 12/08/2021	Dr. Tseng is not a bad professor. I believe the proper way to describe her is strict and highly expectant of her students. She originally worked in UCLA from what I've heard from other students so its not too surprising that her exams are more difficult than the other teachers. Students in this class have lower averages on exams than other students with other professors. If you want to start off in a chem class that challenges you and prepares you for future chem classes, I recommend Dr. Tseng. However, it can often be discouraging in this class when you study as hard as you can and still end up failing the exams. Choose her at your own discretion. Her depicted curve is pretty gracious so far and it will probably be MORE gracious after the final. I don't like the fact that she made her exams after holidays, but I appreciate that she is sticking with the syllabus she made before the first day of classes. The class has a very rigid structure and it is difficult if you underestimate how much studying you need. Always attend discussions because attendance is mandatory and you lose points. She has practice exams which makes the midterms a bit fair. The first and second midterms were very fair because their structure was close to the practice exams. However, the third midterm was not very close to the practice exam which may account for why it was the worst midterm in the whole class. Just be prepared for the unexpected with Dr. Tseng and put good effort in this class and you can manage an A or B with her depicted gracious curve.
Heather Tienson-Tseng CHEM131 Expecting an A- Anonymous 12/08/2021	Dr. T is an okay lecturer- she adequately teaches concepts however she rushed through difficult concepts. For example she spent two to three lectures on the whole thermodynamic section, but she spent the same amount of time on hybridization. Her tests are unnecessarily hard compared to the practice problems in lecture and homework. Most of the questions, if not all, on the tests are application problems (problems you have never seen before) which would be fine yet she gives very long tests. There simply is not enough time to figure out how to solve all the problems on the exam. Class averages were not high and she does not like to give out curves. If you are not strong in Chemistry or have not taken AP Chemistry before do not take this professor. I am only expecting an A in this course because Chemistry is one of my strongest subjects.
Heather Tienson-Tseng CHEM131 Expecting a C+ Anonymous 12/07/2021	Terrible. She does not explain anything, she does not write in a legible manner, she should not be teaching period if she doesn't learn to explain what she is doing. Half of the time she gets the question wrong herself. It seems like she does not know the content during lecture, she simply reads off of her slides and she has an attitude in class. Her exam averages are below 50. DO NOT take this class with her because you will not do well.
Heather Tienson-Tseng CHEM131 Expecting a C+ dino821 12/07/2021	Worst professor I have literally ever had. She does not explain anything and the exams are incredibly hard. Discussion worksheets, homework, and study guides have absolutely nothing to do with the exams or lecture material. Her handwriting is impossible and has TopHat clicker questions. Save yourself
Heather Tienson-Tseng Anonymous 12/07/2021	To put it in simple terms, this class was the worst. During the lectures, she would rush through all the slides we had and when someone would ask a question she would either avoid it by moving on to another topic or call a 30 second break while she tried to figure it out. It seemed like she was learning the subject along with the rest of us. The study guides were nothing like the exams, and even though we all studied our hardest everyone ended up failing our tests. She would make us do exam wrap ups where we would write how the test went and how she could do better but after all our feedback nothing really changed. She put an exam right when we came back from our first break which made things 10x worse because it was only time anyone could really spend time away from school and all their assignments.
Heather Tienson-Tseng CHEM131 Anonymous 11/29/2021	Not the worst professor ever but not very good. She is an okay teacher but does not give good answers at all if you ask in class. She also scheduled two out of our 3 exams the DAY AFTER HOLIDAYS. Had one exam the day after halloween and the other the day after thanksgiving break. Very messed up. Our class average on the first test was below a 50%. I would avoid her at all costs unless u want to be cramming for a test the whole time u are finally home for thanksgiving after being at school for 3 months.
Heather Tienson-Tseng CHEM131 Anonymous 11/28/2021	Overall one of the worst professors I've ever had. It simply seems that she does not know how to answer questions during lecture and rushes through the slides to a point where students cannot even write down any notes. It's frustrating when I go to class and then have to go back and watch the lecture recording to find the slides I couldn't write in class due to how fast she speeds through. Also, making the last midterm in the course to be the day after Thanksgiving break is just brutal. Are we supposed to be spending time with our families or studying chemistry?? Her curves are imaginary and she doesn't believe in averages, don't recommend this.
