Prof. Pau is pretty chill. She's really nice about turning in homework if you have any problems. Definitely go to office hours, she's clears up a lot of stuff. I know sometimes she can be very unclear, and she can keep going even if the class doesn't get it. I took this course with her over the summer and it was the only class I had, and that may sort of make me biased, but I spent hours each day in the library doing practice problems, which is the only way to learn in this class. But yeah, I'd recommend her to my friends, she's not bad. It's the course really, not her. And the TA's were awsome too, so look for a good TA. lol I ended up with an A-, which is what most of the class got, so don't worry.
