Liggett is a very good professor. But he is sooo difficult. Fainting level difficulty! I'm taking him for 171 while taking Math 170B Math 131A. My feeling that 171 with liggett is more difficult than Math 170B with Chayes and Math 131A with Stovall combined times 2... I literally spent all my time studying for Liggett (almost crying, occasionally) and I still got a B, while getting A for 131A from Stovall (people say she is hard, but her 131A is sooo easy compared to Liggett's 171).

Winter 2020 - The class is fine, but far from good. Hanbaek is a decent professor, who is nice and chill. However, he arrives at class six minutes late on average, and don’t care about that at all. His lecture notes are good, but with some minor notation confusion, so there is no need to attend every class (he basically copies his lecture notes in class). Tests are fair, but the final is too easy as a take home final (class average is around 91%).

Fall 2019 - I don't know what the professor did to make people write positive reviews - most of the student in this class agreed that he is literally the worst professor in the math department. His lecture was extremely unclear, and sometimes when he forgot how to prove a theorem, he just told the class to figure out on our own, saying that it would appear on an exam. His exams weren't hard, but with his teaching, half of the class did not do well. Other reviews said that he was pretty helpful, which wasn't true at all, and he did not care about his students' learning at all. My TA and the workload were the only good things about this class, and all other aspects were just pure crap. Avoid taking this class with this professor at all cost, and if you have any doubts about what was said in this review, just ask others who took this class with him. I suspect that people who wrote the lengthy positive reviews either wanted to trick others into suffering through this class like they did, or the professor made them do it - his 170E reviews are much more accurate than the ones on this page.
