How to study barrons AP psych?

I took the class last semester and I take the test beginning of May, so I have a month and a half to refresh my memory about my material. I just bought the Barron’s test book. How do you guys recommend studying with that book? Like, how much should I read a night or a week? Should I read it multiple times through? And should I highlight or take notes in the book? And what about all the vocab?

I took the diagnostic test and oh my gosh, there’s not much I remember… so in a way I’m self studying the class.

Thank you!

If you have already taken a diagnostic test and did poorly, then start reading the book now! Read everything twice, highlighting or the way you prefer doing it. They take the other test and review your mistakes.
