If you're looking for a good, straightforward professor for 115A, you can't go wrong with Omer! While his lectures may not be the most engaging, he explains things clearly and concisely. He assumes you have never taken a proof-based math class before, which was helpful for someone like me who has never taken a proof-based math class. He assigns weekly HWs, and weekly quizzes, two midterms, and a final. The tests surprised me because they were a lot more computational, while the homework was almost all proofs. If you go to his office hours, he's a nice guy and will take his time to make sure you understand the material. Overall, would highly recommend taking this as your first upper-div math class with Omer!

Grading: I bombed the first midterm, but learned how to study better for the second midterm and final. I was scared because I heard this class was very difficult, but I ended up doing better in this class than in 33A. If proofs don't come naturally for you, this class will require a lot of effort to complete the HWs and study for the tests.
