Prof. Do is a really nice and understanding teacher! His tests greatly reflected the material we learned in class, the homework assignments, and the practice exams. While the proofs and multiple choice were slightly challenging, if you did all the work, you’d have the intuition to solve most/all of them fairly smoothly. He also made our second midterm significantly easier to account for the protest disruptions. He is super responsive and helpful, responding to emails and staying past office hours to help answer some questions as well.

He’s a very humble guy, tells funny math jokes, and often references math history and pop culture. My only concern is that there was no appearance by his Snorlax.

By no means an easy class, but a very valuable one for math and CS majors. It gives you a solid introduction to proofs and the mathematical backings of computer science. The first half of the class is significantly more difficult than the second, as the latter half focuses on graph theory, which most people find easy and fun.
Prof. Do is the best math professor I had this year and genuinely wants his students to learn. He is an excellent lecturer, as he is clear, funny, and good at answering questions. He posts notes that cover everything we need to know. While his homeworks can be quite long, they are good practice, which is necessary in this class. He is good at gauging how hard his tests are and will give free points on problems if many people struggle on them. That being said, they are quite difficult overall. The key to success is to practice, pratice, and practice some more.
