not bad but not great. my grade was going to be a b+ but i tanked the final which is why it's a c. my ta wasn't very good but he did grade the weekly quizzes pretty leniently. if you're confused def talk to him bc he can be easier to understand than the TAs. lectures are NOT RECORDED and i had a 9am lec so i ended up oversleeping a lot of the time

Very smart guy and good at what he does. But sometimes he would skip "basic" steps that would leave the whole class confused and when asked about it he would say it was some 241 or 246 thing that we should be able to immediately decipher. HW answer keys also omitted a lot of work making it pretty miserable to study for the exams from them since you were relying on your work being right. Despite this, enjoyable class and I can say I learned a lot. Would 100% take another class with Stefan in a heartbeat, but he's no Justin :)

I had him for both MATH241 and MATH240. His exams are fair, his lectures are engaging, and his notes are very easy to follow. There was no curve for either class and no recorded lectures but they aren’t needed. He makes learning difficult concepts feel easy.

stefan seems like a good professor but i didn’t really like his teaching style since it was literally all just kind of reading straight from the textbook. linear is a relatively theoretical and i felt like i learned better just reading the textbook. also, my ta would just tell us to do our homework during discussions which made discussions a little useless. class is very test/quiz heavy, with the only non-quiz material being the 4 matlab projects (very easy). the tests are pretty fair though, and as long as you do the homework + some of the practice exams, you should be good.

Great dude, very very fair exams. I skipped most of the lectures because it was in the morning, but I could mostly stay up to date because he never strayed from the textbook. The only problem is that 85 percent of the class is quizzes and exams, which is rather heavy, so you have to do well on those because there is no other significant way to bring your grade up.

I love Stefan. His personality and teaching style led to really straightforward and engaging lectures. He was always open to answering questions in class and gave really quick, thorough, comprehensive answers; he knows his stuff. Especially for him not usually teaching linear, I was thoroughly impressed. He never made us do hard applications of linear algebra and kept applications of subjects pretty simple throughout the semester. Exams were fair, sometimes a little difficult and sometimes a bit of a time crunch, but not bad. 3 midterms and a cumulative final. He doesn't have required homework but has practice problems posted if you want or need. Quizzes in discussion once each week, usually pretty easy. Four pretty easy MATLAB projects throughout the semester. Would absolutely take him again because his lectures are crystal clear and he doesn't expect too much of you.

Prof Stefan is a great professor. I have had him now for both MATH241 and 240 and his teaching style was exactly the same: to-the-point lectures, optional homework, one quiz a week, and 3 exams with a final. My only gripe is that is if you do bad on one exam, it will have a huge impact on your grade so stay locked in for the exams.

Stefan is a great lecturer and has relatively easy midterms, which are worth 15%, 15%, and 10% of your grade (10% is your lowest grade). Every week you don't have an exam, you have a quiz in one of your discussions, which are different for different TAs from what I've heard. Personally, my TAs quizzes were very easy and often only 1 question. Quizzes make up 10% of your grade, and the lowest one gets dropped. There is no homework for his class but I would recommend doing the suggested textbook problems to keep up. Other than this, the final is worth 35% which could have a large impact on one's grade, but if its anything like the midterms it shouldn't be too bad. Take 240 with Stefan.

Awesome professor who is funny in lecture and understood that while MATH410 is a very important class it is also typically the first rigorous math class a student takes. There were weekly homeworks that were difficult but doable and the three midterms and final were quick but fair. Also there was a 24h no penalty grace period with HWs which was super helpful. Not so much related to Stefan but the textbook for the course is worth every dollar and probably one of the best I have ever bought. All in all Stefan is the GOAT.

I struggled a lot with Calc 2, but Calc 3 with Stefan was a breeze. He's a really chill and friendly guy. Stefan is a thourough lecturer and his drawings are neat and clear. His exams are straightforward and directly reflect the content of the course. Four exams with the lowest one supposedly out of 50 instead of 100. The quizzes were also fairly simple and there was no graded homework. There were three MATLAB projects, which were a bit tedious but it's a lot easier if you have people to work with. Stefan's lectures combined with Justin's youtube videos really helped me understand Calc 3!

Stefan is great! In the beginning of the semester, he said that he's not as amazing as Justin. I think they each have their own strengths. Stefan is great if you have a solid grasp on basic algebra and trig knowledge and you learn from doing a ton of practice problems. Justin is a bit slower and is more catered to the person who has a bit of a rough math background. That being said, I thought Stefan was great even though it had been 3 years since a last studied math. His exams are straightforward, if you know the topic it is an easy A. His group work can be quite a challenge, but with the help of your TA and peers, you can get through it (and its also graded on participation). There are quizzes almost every week, but they are also straightforward (they count for a good portion of your grade). There is no homework, but there is suggested homework. I'd recommend doing the ones for the topics you don't understand well. If you don't understand things, go to his office hour. He's super chill!

Stefan is by far the best Professor at this school. His exams and quizzes are fair. For groupwork all you have to do is show up and put a little bit of effort in it and you will get a 100. His lectures are very helpful and he does problems very similar to the exam ones in class. If you don't understand the material, he will take time after lecture to clarify the information. His TAs are very helpful as well. He made Calculus 3 very easy to comprehend and I felt I genuinely learned a lot this semester. TAKE STEFAN IF YOU HAVE THE CHANCE!!!

i had math241 and math246 with stefan. in both classes, the lectures were structured very well. exams were easy and straightforward. that said for both classes, especially math246, practice outside of class is absolutely necessary to succeed. For math246, there was no homework, only matlab projects and exams. for math241 there were discussion quizzes and matlab projects, but exams were weighed less. only thing i didn't like was the lack of lecture videos or lecture notes, if you miss a class you gotta get class notes from a fellow classmate.

I have taken upper level class like MATH405, MATH410, STAT410 and did pretty good with them. I've heard that stefan is great and was really looking forward to take AMSC460 with him, but honestly, I am kinda disppointed. I am not sure why this year is really different from previous year (it could due to change of textbook we used in class). First of all, his notes and lectures are kinda unorganized. Sometime I feel he brings some randomly points that are necessary but just don't explain it further, which makes the lectures hard to follow and also makes me feel stressful. Also his use of variable name randomly change and not matching, (sometimes do bring new variable without explaining the constraint on it). Secondly, I personally feel his problems wording for homeworks and exams are somehow confusing and not consistent. The solutions are usually good, but I am struggling to figure out what exactly he is asking. There is usually one or two typo in the homework which making life much harder. Finally, the exam2 we have this year is really different from the previous year. The exam2 for all past semesters have 4-5 questions, but we got 8. Overall, he is a nice guy. He probably did really good for other classes and for past semester, but in my opinion he is somehow unorganized and making things harder this semester. :(

Had the opposite experience as others. This class is statistically known to be the HARDEST class for math majors by far. From my experience, he would always leave proofs half written and have students figure it out on their own, and sometimes he would look at his own proofs and find small errors. Before exam day, students requested he go over the whole practice exam for review since it would be great knowing the difficulty of the material, but he simply refused.

I took this course in SUMMER and it was async. Professor Doboszczak is good at teaching. His notes and videos are fantastic. Homework are challenging and you need to spend long time on them. The exams were all multiple choice questions and you need to be familiar with all the important things. The total grade was fine and I did good job.

Professor Doboszczak is a great professor. As an engineering major I have taken just a few math courses throughout my degree.... and Stefan is definitely one of the best I've had. He doesn't just go over the most basic example in lecture and give you the hardest problems to solve for homework. He gives a great balance of examples and theoretical explanations and gives challenging but solvable homework problems. He gives great practice exams and plenty of additional resources to learn the material. The only downside is that he doesn't release answer keys to the practice exams. So you should work on them well before the exam so you can get assistance from him or the TA's if you're stuck. The course, though being titled computational methods, has a lot of cool information regarding the IEEE floating point standard, how computers store numbers, and how to figure out how accurate your answer can be on a given machine (single precision vs double precision). The second half of the course I found to be more challenging as it is the more theoretical mathematical concepts you see on the course description (interpolation, quadrature, differentiation, etc). I was weary to take this class after being required to take so many math courses -- but I actually enjoyed every lecture I watched because of Stefans teaching. I would 100% recommend this course to anyone that has the option to take it.

Stefan's a nice guy and pretty smart but he isn't good at teaching the material in an understandable way unlike other Diff Eq professors such as Kendall. He does not really teach the concepts or reasons around topics, so you'll have to learn it outside of class or learn from your peers who took another professor. His exams are a little too easy, and it sucks because the average is so high and making a mistake will put you below. His exams also don't prepare you for the culmulative final, because his exams were much easier than other professors'. When reviewing for exams, I found that a lot of my peers who took another professor were taught to actually understand the material and taught helpful shortcuts and tricks. It will help a lot if you took linear algebra before you take diff eq, and you won't have to learn it outside of class because Stefan went over lin alg basics once and expected us to be knowledgable on a lot more when most of the class has never taken lin alg (bc its not a pre-requisite).

Stefan's teaching was well organized and clear. In general differential equations is a tough class that covers many, many topics however his lectures covered everything that was necessary. Stefan went over several examples in class to show us how to do the problems. His lectures were straight into the point, but he also provided some intuition for why we did certain things. Most of it was just applying an algorithm or formula though. In addition, he provided suggestions from the textbook for the class. This was never required, but doing these problems strongly prepared you for his tests. The only graded homework we had was MATLAB assignments, which were fairly easy (you had infinite attempts). The tests themselves were fair. The problems were similar to those from the textbooks, so if you studied those and went to lecture you should be prepared. The final exam was more difficult however, but it was a common exam between all lectures. The grading on these tests was fine, and his averages were higher than other professors.

Stefan was great. Decent lecturer and would focus on the important information and not waste time on overly wordy proofs (unlike Gulick for Calc 1 and 2). The course structure was amazing. There is a great balance between non-exam and exam grades. The grading is clearly outlined and followed throughout the semester, we even got more quizzes dropped in the end. The discussions were very organized with a groupwork worksheet on the first day of the week then a quiz on the second discussion of the week. Exams were extremely fair and usually followed very closely with Justin's exams, which makes studying for them very intuitive. I would go out of my way to take Stefan again.

Stefan is a pretty good teacher. I think his exams were also well-designed. Never any trick questions. If you did the homework, you can go into the exams fairly confident. And there were no quizzes in discussion sections or anything, so you can safely skip them. The only thing that bugged me a bit is that he switched from synchronous to asynchronous lectures a week into the semester. I prefer synchronous lectures, but it's not that big a deal because Stefan was active on Piazza, so you could still get questions answered there.

In my opinion, Stefan is one of the best math professor's at UMD. His lecture's are clear and easy to follow, and he teaches with a lot of personality, making the lectures more fun to attend. He assigned homework once a week, but was very flexible if we needed an extra day or two to complete it. If you go to class and complete the homework you can do very well in the class. I HIGHLY recommend taking him for any class if you get the chance.
