This is the second class I took with Prof. Nurbekyan and so far he's the best instructor I had. He explains every concept really clearly and really cares about student learning. I felt like he gave a great understanding of not just the concept but some of its interesting implications, and at the end of the quarter I felt like I had a great grasp of the concepts taught.
The class itself sounds really interesting at first, but then there was lots of physics involved which is least favorite topic for almost every math major. Syllabus consist of 20% hw (typically 5-6 question but grading on it was pretty tough), 15% group project (which was very engaging and helpful), 35% midterm and 30% final (which both where really difficult to solve)

The structure of this class is a bit weird, but the professor is kind nonetheless. What is taught in the class is not really related to the homework, which is also not really related to the test. But I think if you master the basic understandings, then you should be able to solve all those questions.

Class is a little bit awkward because everyone has zoom shyness, but there was one time when the professor asked us to speak our mind on a certain topic and the class was silent for like, a full minute. I felt so bad for him, but it's not really anyone's fault. Professor is kind and nice, but just a little bit too awkward

Overall, Professor Nurbekyan was a good instructor and adapted his class to the virtual format well. As mentioned above the grading on homework was tough so would recommend going over it with peers and/or attending OH. Additionally, the finals were 24-hour take-home, during which time Prof. held an additional OH to answer any questions. Exams were graded similarly to homework. Final note - a portion of each topic was dedicated to connecting the math to its physical interpretation, so I found there were more conceptual assignments (like the project) than other math courses
