Taught by Garrity, this is an easy and entertaining class if you're already a math whiz who plans to do a PhD in math. Homework is optional, but TAs will grade it if you do it. There are weekly quizzes, but these involve only one or two problems from the previous week's material. There are three exams, and about 10% of the class received a 100 on each of the first two exams. A significant portion of the class received under 70%, and a handful scored under 50%. On the other hand, the  The third exam involves long and demanding proofs of complicated theorems, and is notoriously difficult. Beware if you are not confident with doing mathematical proofs. Many students who were good at math in high school found that the quizzes and exams were very difficult to do well on. If you've taken Calc AP BC, which presumably everyone in the class has done, there's very little material that is really new. One person got an A on about half an hour of work per week. Most people needed to put in at least two to three hours of solid work per week, and still found difficulties in the later parts of the course, which introduces complicated theorems.
