Ellenberg was the best professor I've had in the math department at UW. He cares so much about his students, writes doable exams, and gives interesting lectures. Homeworks were challenging but really reviewed the lecture content well and prepared me for the exams.

Homework sets can be long but fair. Exams are made on the easier side because he uses it to test fluency and not depth. He really wants you to enjoy the content and stay hungry. Great lecturer, entertaining, and inspirational. A true GOAT at Madison
