Winter 2020 - Reise is an awesome guy, but his lectures were all over the place and hard to follow/understand. If you zone out for even a minute, it's so hard to get back on track. A lot of the slides are just random screenshots of code with arrows pointing to certain things, but no explanations. The online textbook is eh. The practice quizzes at the end of the chapter and the practice quizzes he sends out are pretty much exactly the same as the five weekly quizzes throughout the quarter, so study those and you'll be fine. If you have any kind of stats background, you should be fine for this class. It's an easy A, I just didn't study enough for two of the quizzes and it hurt my grade.
Personality Psychology is a pretty interesting class. While the lectures weren't extremely thrilling, they were fairly entertaining. There was only a midterm and final and both were composed of multiple choice questions. As long as you read the book (which isn't hard reading at all) and study his lecture notes (which he posts ahead of time on the web), it is easy to get an A.
