Last year he told us what's in the exam -- went through each slide indicating what's important, and what he'd expect us to know. My advice: go through the ilecture and take note of the hints/explicit information he gives, because that effectively IS the exam. It's hard to say this without sounding like I'm bragging, but to demonstrate how based on the lecture slides the exam is, doing the above got me an HD. Learn what he tells you to, and you'll be right. From memory (As you'd expect in psych exams) some of the questions are a little tricky, but with a deep breath and a little logic you can work it out.
Does that help?
(Good luck!)
