I never took (in fact, my high school didn't even offer) AP psych. I had only a little background in psych when I bought this book and read it cover-to-cover. I requested a special testing session at my school and I got a 5 on the test, getting me out if intro psych at the U of M. So, if you're willing to put in some serious and concentrated study with this book, I think it will be a great help. I owe a lot to it.
