Reviews of professor Sudipta Kolay

Rating: 2.0/5, difficulty: 4.0/5
This class was tough from the start. I never understood any concept from lecture alone. I always had to read the textbook thoroughly on my own. The tests are difficult and very important to your grade. From what I understood, this was one of the hardest linear sections. I didn't find the final as bad, though. There is a slight curve at the end.

Terrible at explaining concepts, but it's apparent he cares a lot about his students and puts a lot of effort into this class. His section of 1554 is harder than every other section I've heard about by a wide margin. Be careful too - it's incredibly easy to fall asleep in class because the lectures are not engaging in the slightest. Tests are hard.

Professor Kolay seems to be very tough in the beginning, and he is. But if you actually read the textbook, attend most of the lectures, then you should be pretty solid in the class. His office hours are as helpful as you make them, so be prepared with questions. The TAs are your best bet in this class, but overall the content is not hard.
