Extremely challenging exam + confusing lecture + no curve = Raul. He is the worst professor I've ever seen. The midterm is extremely hard. I got A from Math4A to Math6B, but for Raul's Math6B, I'm wondering if I could get a C. If you want to destroy your GPA, select Raul.

Alonso is a very nice professor. He grades very leniently and is super helpful in office hours.

His ability to copy the textbook onto the blackboard word for word is honestly impressive. He's very nice and a reasonable grader but it's hard to learn anything through lecture. Sections are a lifesaver!
