Spring 2025 - This was a solid class. Giulio is very approachable and wants student to succeed. Sometimes the material can get confusing during lecture and explained poorly, so some self-studying outside of lecture is necessary (at least for me), but he is not a bad lecturer at any means. The best part about this class is that his tests are fair; the difficulty is similar to the practice exams, and they won't have anything you haven't see from the homework or practice exam. The average for the midterm was pretty high. Side Note: I also highly recommend taking Giulio for Math 170E if you can, (I honestly think he teaches that class better than this one).

Winter 2025 - Math 170S with Gurdogan is a strange class. First of, be an expert in 170E. He loves use Binomial, Exponential, Gamma, Beta, and Chi Squared distributions. A lot of profs skip some of the later stuff, but he will assume you are experts on them for the test. He also gives absolutely no practice, especially for Bayesian Statistics (one of the hardest topics), so maybe ask GPT to make some hard questions involving that. The second half of the class is almost entirely plug and chug, and the MT was significantly harder than the final because of that. He also goes into many tangents on proofs which he never tests on and lecture isn't very useful compared to slides.

Spring 2024 - I often got lost in the lectures and found them very hard to follow. He posts his notes but I found those confusing as well (and so have other people in the class). I feel like he didn't give us enough homework and he ended up testing us on things that we've never even practiced. Since his lectures were confusing and we barely got any homework I wasn't really sure what to study for the final. *He only gave us three homeworks for the entire quarter (each consisting of 5-6 questions). He's a very nice guy and will try to help you if you ask but I just felt like we didn't get enough practice so I was lost for most of the quarter.

Fall 2020 - After reading all those "great" reviews for this professor, I thought its a good choice to take Math 170S as one of my elective class, but I can't describe how awful this class was. Imagine someone just reads you the lecture note pdf that is already uploaded, word by word in slow motion and leaving the questions unsolved, then having a quiz every other week which takes so much time with only 2hr limit time. (Btw if you f*ckup your midterm, quizzes will worth 50% of your grade so really be careful on quizzes). Finally both midterm and final was the worst and impossible to pass since the instructor will be grading it himself with absolutely no partials. My advise: This class is far away from being easy and useful, so don't waste your time on taking Math 170S with LYU and try whole quarter to pass the class, either take someone else or ovoid probability and stats.
