Jiwoong Jang MATH241H Expecting a C Anonymous 01/07/2025	This was his first semester so I hope he will get better but please do not take him if you have options, the other two 241H professors (Jeffrey Kuan and Junyan Zhao) were much better which I heard from friends. If not then just take the non honors section. Lectures: Way too fast with the more complex practice problems which made it hard to try them before he showed the solution. He was hard to understand sometimes and did not understand students questions often - not sure if this is an English problem or what - but other students had to speak up and answer other students' questions that were directed toward the professor because he did not understand. Wednesdays were the quiz days which were 25 min and 2 questions usually which is nice as you can get out a bit early but the quizzes as he said were supposed to be very easy and much easier than exams is so wrong after the first few weeks. They got very difficult as the course went on, the only thing you can do for practice that he gives are textbook problems but the problems he writes are not similar to textbook problems so you just need to be really good conceptually and just hope the problems on the quiz aren't too bad. To be fair the quizzes were graded lightly with much partial credit averages were around a 8/10 but very hard to get 10/10. Exams: The exams were harder than other sections just because the practice exams were not similar to the actual exams. My best advice for the exams is to study the quizzes as some quiz questions were basically the same as the exam questions. Also the third exam was the week before finals which the math department does not allow but I guess Jang just doesn't care. Final: The easiest part of this dudes class is the final, the average of our class final was a 90% and the average for other sections were about a 75% - 80% which is absolutely insane. Maybe Jang's class was full of smart people but I just think this happened because everyone wanted a better grade than what they had because the midterms were so hard to we all study so much for the final which is not written by Jang meaning we would actually be prepared with the practice finals as they are similar to the final. Curve: He lied and said our final grades would be curved but they were not curved at all. I got a 90% on the final and got a C in the class which is insane - I emailed him about it and no response - most professors would realize you actually learned and would bump your grade up a bit. Homework: None unlike other sections which is nice work load wise but does not help the grade at all as most people get 100s on homework. Advice: Look up justin wyss umd calc 3 on google for notes and practice finals/tests he is also on youtube. I watched a YT channel called Calculus III which did the same exact sections and went over textbook problems which was very helpful: https://www.youtube.com/@calculusiii8878 . Final advice is to go to his office hours after getting your tests back, he will probably give you a few extra points if you question some things. Good Luck.
Jiwoong Jang MATH241H Expecting an A+ Anonymous 01/07/2025	Professor Jang is an extremely nice guy who did seem to want us to succeed. Unfortunately though, I found it really hard to follow him during lectures, and whenever I asked for clarification, his explanation made me more confused. I had to spend a significant time outside of class reviewing from the textbook, which definitely saved me. His class is definitely doable and his exams are fair for the most part, but from my experience, you will need to put in a good amount of work outside of class. He did have a curve at the end which was nice.

He is a very nice person and tries to help you understand, but he is still developing his teaching style. It was a little hard to understand him because his English isn't the best. His lectures were basically a summary of the textbook + example problems. Sometimes, when solving the practice problems, he skipped some steps that were "simple." I took this course in high school so I understood what he did but a lot of people in my class were confused. For his exams, sometimes he puts things on them that he went over for like 10 minutes and also things that won't appear on the final (ex. limits). Homework isn't mandatory, but if you do the practice problems he suggests, you'll do fine on the quizzes. Sometimes the quiz questions are just questions pulled out of the practice problems from the textbook. Overall, he's very nice but a little hard to follow; read the textbook and do the suggested practice problems if you didn't understand lecture.
Jiwoong Jang Expecting a B+ Anonymous 12/09/2024	I think Professor Jang is either a graduate or PhD student and this was his first time teaching a class, and I'm not sure he planned on teaching to begin with since my section of MATH241H wasn't assigned a professor until two or three days before classes started this fall. He taught my class using the example problems out of our textbook, which vary in how relevant they are to our tests and how straightforward they are to evaluate. Some of our exam problems, I felt, were unnecessarily difficult to evaluate and included steps outside the scope of this course. Most of them were pretty straightforward, though--just the application of a single formula. Professor Jang has been pretty lenient with partial credit on exam problems, though, which is nice. His lectures move really fast and he often skips some steps when going through longer practice problems which can make him difficult to follow. After lectures, I always went back to my textbook to review and clean up my notes, and I recommend doing the same should you take his class. My hope is that in future semesters he finds more effective ways of teaching, and I believe he will--he's very patient and owns up to his mistakes. I want to give him some grace for this semester since this was most likely an unexpected, last-minute ordeal for him. I'd rate him 3.5/5 if I could, but I'm rounding up to 4 in hopes that he improves. I'd also like to note that instead of curving individual assignments, the curve for my class is done by changing the grading scale at the end of the semester based on everyone's entire performance. Right now I have an 84 and I'm hoping to raise my grade up to an 88 or 89 by doing well on the final, but I have no idea whether that's going to be a B+, A-, or A. I don't know whether this decision was my professor's or if this applies to all sections of MATH241H or all of MATH241.
Jiwoong Jang MATH241H Expecting an A- Anonymous 12/09/2024	Mr. almost Dr. Jang is a great guy. Very kind and smiley. He did a lot of practice problems in class which were helpful. He struggled to explain some concepts to the class, but you could tell he was trying to get us to understand everything.

The exams were way harder than the posted practice exams and included very tiny topics that were not reviewed much at all. You could get the topic, but the evaluation would be extremely difficult, causing you to lose points. Take someone else if possible.
