Lectures were pretty bad, TA carried the class

I didn't attend any of the lectures, so take this with a grain of salt. I went to almost every discussion though, which is where I learned most of the course content (or at least enough to attempt the homework and exams).

In my opinion, although classmates disagreed on this, the content gets much harder after the midterm. This might be because I didn't attend lectures. The first half of the course is very intuition-based, and if you have taken Math 61 before this, you will have an advantage, since much of it is combinatorics and formal logic. The second half of the course focuses more on formulas and calculus. Going to lecture or reading the textbook becomes a little bit more important here.

Tonmoy is an amazing TA, and I would highly recommend taking a class with him. He seemed to be the one running the class instead of the professor. If you have him, make sure to go to discussions and ESPECIALLY the exam review sessions, as homework is often based off of discussion problems and exams are very similar to the problems covered in review.

The homeworks are quite difficult, and you probably will need to work with others or go to office hours. While I personally never went, I'm told Tonmoy's office hours were very helpful. The midterm was pretty easy, while the final exam was quite difficult. You are allowed a cheat sheet and calculator. Definitely study for the exams.
