Spring 2020 - The Math department is trying to make this class rigorous however I believe the syllabus has not been well-developed (yet?). While the class attempts to introduce Probability as Measure Theory, it does not go in much detail, leaving students only confused. Overall however, I did learn quite a bit from this class and would recommend 170A over STATS 100A to anyone who wants to learn Probability in a little more depth. Professor Rebrova definitely knows her stuff but is not a great lecturer. The lectures are not clear and organized and I often am confused at the end. However, Office Hours are useful and she answers your questions very clearly. She has taught probability before so it might just be the change in curriculum that affected her teaching so maybe give her a chance! FYI: For this virtual format, most of the grade weightage was given to quizzes (best of 4 out of 5 count) for a total of 60%!!! In general the exams and quizzes were a little tricky.

Pretty good professor, very different from those negative comments. He did give us a very hard second midterm, but he lowered the total points from 55 to 50, and he assigned very few points for the hard problems. The final was super easy. I spent 40 minutes and handed in my paper without double-checking, and I still got an A.

Professor Richthammer is a really good professor. He really understands what he's lecturing, and does a good job balancing theory with examples. For lower-division classes, I could imagine him putting in more theory than is necessary, but once you hit upper-division classes, you should expect to get theory no matter what. His homework and tests are difficult, but he is a very generous grader. I struggled through the class, and still managed a B-, which I personally thought was higher than I should have received. He is also extremely approachable, encourages you to ask questions, and can be reached at office hours or via email very easily. Overall, he's a good teacher that will push you to understand the material, while not grading too harshly at the same time. Highly recommended.

Winter 2016 - He is a good lecturer. He has clear and thorough lecture, and a beautiful handwriting! The homework problems are hard, but that's not made by him. That's the problem set commonly used by the department. His exams look quite similar to homework problem, and there is no surprise in the exam. Try to understand the homework problem thoroughly and it should be sufficient to deal with exams. One of the drawback is that I think he only gives 20% A and A-.
