Things can get a little confusing in class, so I would recommend skimming the material before lecture.  Otherwise the material for the class was very interesting and not too hard.",

Her slides are posted online, but I can't seem to learn when she is going through in class, which is problematic because she will do pop quizzes. Exams are hard. Homework is manageable. Book is excellent, she just reads off of it.",
