Alright, my AP Psychology teacher was an idiot, he knew nothing about the subject and just read off of an teachers guide the entire year. After our first test in that class, everyones grades DROPPED. I pulled of a 70 on the test. Next chapter I studied harder, and while looking for some online practice tests to help me study, I came across a site that really, I mean REALLY helped me out. At first I thought it was just another practice test, so I took it to see how well I knew the information, then checked the answers with the ANSWER KEY on the site. So it wasn't until the next day that while taking the actual test, I noticed that EVERY SINGLE QUESTION WAS A QUESTION FROM THE WEBSITE I JUST FOUND. Needless to say I aced that class the rest of the year and still managed to pull off a 4 on the AP exam.
Heres the site, hope it will help you as much as it helped me. Also I hope your teacher uses these tests'.
