Lectures: quite challenging in the online environment. His slides can get really full and difficult to decipher, and he's not the best at online lecturing.

Discussions: really nice to be able to hear the concepts explained by another person, and he has good exercise problems too

Homework: good practice for the lecture concepts, but does not seem to reflect the type of questions he gives on the exams

Exams: tends to include some conceptual questions and a lot of letters (very little numbers). They can be quite difficult.

Overall: he's a really nice professor but he doesn't always teach you everything you need to know. There are YouTube channels which you should definitely watch on top of his lectures, and expect to have to study beyond looking at the resources that he gives.

Chatterjee has quite a lot of experience in teaching, but he just has a really soft voice that is difficult to hear if you sit in the back of the room. Even when I sat in the front of the room it was kind of difficult to hear exactly what he was saying. Nevertheless, he's still a good professor, but his lectures are REALLY dry, especially after the midterm.

We had lecture for two hours, but instead of taking a break in between, he decided to give a 100-minute continuous lecture and let us out ten minutes early; supposedly, it's to maintain the flow of lecture, but it would really help if we got a 10-minute break during lecture. Given his really dry lectures, only about 20 people (including me) showed up to lecture during the second half of the course...and among those 20 about half of them were asleep during lecture. I, myself, had to lie down on the floor right in front of Professor Chatterjee (but he didn't mind me doing it) just to keep myself alert in class.

The homework assignments were majorly time-consuming, and if you don't have the solutions to the assignments, you'll most likely be spending most of your weekends trying to do a lot of complex math and figuring out where you made your mistakes.

Chatterjee can be pretty tricky on his exams, and I thought he was a little unfair during the final. During class, he said that he didn't want us to take the time to memorize formulas and that he would give us a formula sheet. But during the final, he didn't even provide all the formulas necessary to solve the problems!

Nevertheless, I got an A in the class mainly because my TA was pretty good in discussion, during which she would go over a few problems in the textbook to give us an idea of how to solve our homework; they weren't exactly the same problems, but they were able to force us to learn the different methods of solving problems.

Professor Chatterjee is the best professor I've had at UCLA. He is like a loving grandfather- always concerned about his students and makes sure everyone understands the material. He even gives us his phone number so that we can call him for questions. No other professor has done that for me.

His tests are fair, especially since he tells you what will be on it and makes sure you understand all the material. Overall, he's a wonderful persona and a great teacher.
