Winter 2021 - Unlike other students who leave comments, I find this class with Professor Iseli easy. Weekly homework is the major component of the workload, but I only spent ~2-3 hours on average each week on homework. The two quizzes require a decent amount of time to review. I spent like two hours on reviewing the notes for each of quizzes. Since the final was 24 hours open book, I didn’t even review before the exam. This course is chill in online format. Professor Iseli is clear, caring, and supportive, although it could be a bit hard to recognize her handwriting occasionally. I would recommend anyone interested in 170B to take it with her. You should be familiar with analysis before taking this class, otherwise you can lose points anywhere because you made minute mistakes in real analysis. This course requires more rigor than usual undergrad classes.
this is possibly the hardest class i have ever taken in my life. the homework problems are hard but if you finished all the homework you should be fine on the final the professor is every helpful during his office hour however he is going to retire so i guess no students will come to check the ratings & comments
