Spring 2021 - Overall, I think this was a good class. The professor was a bit dry, but the lectures were very clear. The class did get a bit overwhelming, but if you stay on top of your work it isn't too bad. There is weekly homework that takes about 1-3 hours and is good practice. Both his midterm and final exam are difficult, but I was able to do well because of the practice materials he provided. He gives you a practice midterm and two practice finals, both of which were similar in the topics/difficulty of the real exams. The final exam is cumulative, although there was a surprising emphasis of the latter half of the course on the final exam, in particular on the concept of expectations. There were two versions of exams (because of time zones) and you had to take the same version of both exam (so if you took the morning midterm, you had to take the morning final). The said class was curved such that the top 25% got an A, the next 35% got a B, the next 25% got a C, and the last 15% got a D or worse. I think he was slightly more generous than this and if people do well, he isn't afraid to curve down. In addition, both versions of the class (those who took morning exams vs those who took evening exams) were curved separately in case the tests were of different difficulty. There are two grading schemes: 1) 10% HW, 30% Midterm, 60% Final 2) 10% HW, 90% Final He will curve you in both grading schemes and then whichever one you have the higher grade in, is your final grade. The medians for the midterms were: 77% for morning, 83% for evening The means for the midterms were: 76% for morning, 79% for evening The medians for the finals were: 83% for morning, 82% for evening The means for the final were: 81% for morning, 79% for evening I would recommend taking this class, it took me a lot of effort to do well, but it was doable and he was a fair professor.
