If you are getting ready to take the AP PSYC exam you need to get this book. It contains quizzes on each section of psychology and two practice full length tests at the end. It also has very helpful tips for writing essays. I took the AP exam in the spring of 2005 and got a '5'. I am now a freshman neuroscience major at the University of Delaware (one of the best schools for psychology and neuroscience) and have passed both of my two psychology classes with A's (the highest grade). This book is a must have and I refer to it often.
