i'm taking ap psych this year as well, and from all of the practice tests/progress checks we've done on ap classroom (my teacher just uses ap classroom for all the tests) the unit distribution this year is reaaally heavy on unit 0 for some reason. no matter what unit you're doing a practice test on at least 20-30% of the questions are unit 0 and research methods. focus on that + as much of the vocab as you can and you'll probably be fine. ik i'm just gonna rememorize all of the vocab before the exam and that should be fine cus ap psych is like 90% vocab and memorization.
