Winter 2018 - WARNING: STAY AWAY FROM THIS PROFESSOR If you have the option to not enroll in Lei He's class, you have been warned. His course was the single worst course I have ever taken at UCLA (and this is having taken and done well in courses like CS111, CS35L, etc.) His lectures are abysmal. He takes screenshots of the textbook and haphazardly throws them together into a poor excuse for a lecture. During class, he is completely unprepared and proportionally incomprehensible. No one can understand what he is saying, and I honestly don't think he understands himself. Worst of all, his tests are written by the TA's. The TA's are on a completely different page from the professor so they ended up asking completely irrelevant questions. In one case, there was a page of questions on a set of slides that Lei He specifically said not to study and replaced with an "alternative" set of slides. His TA belligerently told us that the concept was a "prerequisite" when we asked for further explanation. This professor blatantly lies about what's coming because of this TA-professor disconnect. He happily told us many times that the test was "just like the homework", or that his review slides would EXHAUSTIVELY cover the test and that the test would have "no more, no less". On these tests we would have many concepts that we've simply never encountered before. Also, he was gone for the first and last weeks of class to go to China. I am not sure him being here would have made much of a difference though honestly. PLEASE DO NOT TAKE THIS CLASS WITH THIS PROFESSOR IF YOU HAVE THE CHOICE.

Winter 2018 - There is WAY too much negativity on Lei He here and I won't stand for it. He is a great professor. Prof He was always willing to take the time to answer questions and provide additional explanations, and they provided a variety of resources and learning opportunities to help us succeed. They were also very fair and consistent with their grading. I highly recommend taking a class with Prof He. While it may be intimidating at first to have a professor with a bad reputation, I can assure you that Prof He is actually an amazing instructor who cares about their students and is dedicated to helping them succeed.

Winter 2019 - I know Lei He doesn't get a good rep on BruinWalk, but I have to back up my boy here. Although I was a computer science major (graduated last year), Lei He's classes were two of my favorites at UCLA (M16 + M116C). He explains things in a shockingly great way, you just have to get past the accent (which most UCLA professor have, anyways he's trying his best). Honestly he does an amazing job and as someone who went through the gauntlet of the 'toughest' classes at UCLA I can tell you this is nothing to worry about.
