Professor Varvarezos gives me hope for the future of mathematics educators. He is very thorough in lectures and gives many examples, so taking notes go great. He also videos his lectures on Canvas, although the camera work is often so bad and annoying that I'll just go in person. His grading schemes are very forgiving, with an option where you can even drop your lowest midterm completely with more weight on the final. Test questions are very accurate to the practice sheets he sends out, with some variations in types of problem but with similar concepts. You get to make a cheat sheet for exams; both midterms were very straightforward, and the final was easy but utilized more critical thinking. Varvarezos is also very helpful in office hours, both on Zoom and in-person, he is great at explaining!!

I loved this class so much! I highly recommend Professor Varvarezos because he is such an engaging lecturer. He always pauses to ask if anyone has questions and answers them to the best of his ability. He draws very informative figures that help students visualize new topics well. I've attended a couple of his office hours and I would definitely say that it was worth my time! Overall, Professor Varvarezos is super approachable and very understanding. 10/10 experience.

I didn't go to lecture because all lectures are Bruincasted. He lectures very timidly, but he gives a lot of examples and answers questions well. I didn't find the content of this class all that hard, and it was pretty easy for math 32b I think. Homework is 15% of your grade and he drops your lowest grade (you can definitely get 100% on this section). Reading the textbook is good for homework. Discussion is 5% of your grade which is annoying for a math class but if you do 8/10 worksheets you get full credit, plus some bonus if you do some surveys. Midterm weight depends on if you drop one, but the two midterms were ridiculously mind numbingly easy. Aced both. 4 simple questions that most of the class finished in 20 minutes and we were given two hours. Average on first midterm for my lecture is 97%. So I think he's going to try to amp up the difficulty lol. Which is probably appropriate. Basically, don't study for midterms. The final was harder, but omg our piazza was flipping their shit after it because it was significantly harder than the midterms. This was true, but we still had 2 hours for 4 problems and most people left early. I know this sound very teacher's pet - y, but the final definitely should have been harder because the average on a midterm for a multi class should not be 97%. But literally people were begging this man for a curve, spamming him, while they were walking out the door of the final, like BEGGING. and the average turns out to be a 87.5. SO STUPID. Anyone here who whines about the final at least for this quarter needs to like actually chill. The annoyingish thing about this class is no matter what you have to slay the final. There are two grading schemes and one of them is 45% final and the other is 40% final. Kinda yuck. But anyway, this class is cake, take him.

Konstantinos is a very special man. This was his first quarter teaching out of his PhD program, and he did such a great job. He explains the concepts quite clearly, and is very helpful during office hours. He just seems like a really kind and bright person in general, and he has a sweet demeanor. His midterms were really easy, and if you understood the concepts on a surface level then you would do well. The final was definitely harder, but it was a pretty fair test. There were 4 questions with about 3 parts each, and you had 3 hours in total. He also has a really great sense of humor and being in his lecture always brightens my day. Overall, having Konstantinos has made my quarter and education so much better. If you have the opportunity to take this professor, please do!

Konstantinos is by far one of the best math professor I've had. He is so sweet, articulate and extremely helpful with explanations. The exams are very fair and the homework is designed to help you understand the material the best you can. After our first midterm, we all applauded him when he walked into class. He records lectures, and office hours are very helpful. We also get credit for worksheets that solely help with understanding and do not negatively affect your grade. 10/10 recommend this professor!!

Genuinely one of the worst professors I've taken at this school. He's completely 180d from the old reviews from when he first taught the class. Lectures were never recorded, lecture notes were never posted online, and he refused to give anyone his hand notes and said, "just get it from a classmate".

He's a nice guy, but that's pretty much all he has going for him. His examples in lecture were unbelievably easy which made the homework next to impossible as you had to teach yourself everything. The exams were NOTHING like his lecture notes, and we had multiple types of questions on the final that we flat out never covered. Like the topics were the same but we were never taught any of the applications of those topics that appeared on the final.

Genuinely terrible experience, would not recommend to anyone.

Dont take this professor, the lecture examples are too easy to the point that doing the homework is having to teach yourself the topics again. And the exams were awful, harder than any problems given by the homework/worksheets. The questions on the exams were nothing like the practice. I do not recommend this professor.

Avoid him at all costs! This professor does not care about his students. He made the final exam the same as the one in another lecture, but he never explained the related concepts well. In addition, the other professor has a much better grading scheme (15% homework, 85% exam for us; 25% homework with 3 extra credit points toward the final grade for the lecture with the other professor), which makes it extremely unfair. He even disabled Piazza after students shared their feelings about the exam. The average for the final was around 70, and it accounts for 50% of the total grade. The lectures are terrible as well, with no notes or recordings posted. Overall, he is the worst choice for 32B.

No lecture notes, no recordings at all. This professor is not who he used to be. Do not trust his high score. The major problem is he himself might not even understand his lecture as they seem unprepared. He even took the final of another professor as our final, but the other professor covered all the problem types in his not while VKK did not even have lecture notes. This makes his tests super hard for his students but relatively easy for students in other lectures.

It's...okay. As a class, pretty easy: homeworks were not especially time-consuming or difficult, and the exams were all very straightforward. That being said, it doesn't feel like we learned much at all? Most of the course felt like essentially different ways to dress-up a partial derivative, maybe plus a cross product if you're feeling spicy. If you handed an above-average 32A student our formula sheet and gave them our final, they would honestly probably pass. No other major downsides, the lectures were okay (lots of examples, some neat drawings), but I do feel somewhat let down by this course as an elective. This class only talks about curves and 2-manifolds, so do keep that in mind.
