32B was such a useful class. Professor Wang taught me how intuitive math could be. Sometimes she'd even pull up snazzy visual graphics in lecture to help us develop intuition. My favorite part of this class was how she always provided motivation for what we were studying from day one through the end of the course. The end with Stokes' Theorem was a bit rushed but the remainder of the course was well-paced. The exams mimicked the homework difficulty very accurately and were really fair. Sometimes the exam had repeat HW questions, which made for a solid grade, but sometimes the exam q's didn't exactly test our skill in applying the concepts to fresh problems. Wang is super helpful in office hours and after lecture. She's clear and dedicated to helping students with their questions even if she has to look through a few textbooks to figure it out ( pretty normal she was a phD candidate when I took this class with her). Wang is the best math professor I've ever had. I really wish she taught the 33 series as well.
