Professor Pak is a really smart guy and his lectures are pretty entertaining. He's pretty funny but he gets very angry very quickly. He will call you out if you are talking in class, and if you walk in late sometimes he'll stop class just to glare at you. I'd recommend going since a lot of the specific examples he lectures on have pretty similar concepts to the exams. Tests are average for math department, typical bell curve sitting around ~60. The textbook is pretty awful so I used "TrevTutor" videos on youtube for a lot of the concepts. The Homework Assignments are very long but he recommends you make study groups, which is helpful since some of the questions are incredibly hard and there are so many ways to go wrong in this subject.

Igor Pak is a good professor. He teaches the content in a very clear and concise way. He occasionally makes fun of himself (including his Russian origin and his accented English), which sometimes makes the lecture more interesting.

Even though I had already known a lot about discrete math before I took this class, I still find going to lecture pretty essential. He introduces the theorems and facts, does example problems in class which are very similar to homework problems.

The homework problems are mostly easy, but occasionally there are a few hard ones, as well as a few that's not hard but very tedious to do, like giving you a complicated graph with more than a dozen nodes and asking you to find a Hamiltonian cycle. For those I lost patience after a few minutes of trying and used Wolfram Mathematica instead.

Midterms are not that hard, but the final is significantly harder and more tedious. On the final, there are also numbers so small that they aren't printed clearly enough: eventually the TAs started copying the several dozen numbers to the blackboard. Personally I'm glad that I did very well on the final, but before I saw the score, I was really not sure that I did well and not sure I would be able to get an A: there are just so many possibilities to make careless mistakes. I was pleasantly surprised when I saw that I in fact got an A but I guess it was close.

Verdict: his exams are a bit unpredictable but if you care about learning, he's an excellent professor.
