Mills is a pretty decent professor when it comes to explaining concepts. However, that being said, I would definitely say that she doesn't always prepare you for the types of questions she will ask you on the midterm and final. She is also a bit disorganized in her lectures I would say, so sometimes just reading the textbook is the more efficient way to go. In terms of grading scheme, for the summer session it was very generous and really emphasized problem sets, so that if you were putting work in, it would definitely help your grade. She also offered some extra credit for participating on Campuswire and such. Overall, I recommend the class but just be aware of some of these things. :)
