I took this course with Chang He and I would recommend you take it with someone else. She’s actually pretty nice and wants to help her students (adjusted the grading a lot) but the tests are very hard and long. All my friends took Westerfield and got A+s. Chang comes from LSE and thinks averages should be much lower than we are used to. Again, if you have to take it with Chang, not a disaster, she’s nice and I’m sure will get better, but her class this semester was pretty poor
