Query: The Best Test Preparation for the GRE Psychology Test

After taking the GRE, I realize that this book did not help me in my preparations. All it managed to do was upset me into thinking I was going to do terrible on the exam. The questions were 10x harder than the exam itself. Also, to my chagrine, the book did not have any review outlines in it - an essential part of test preparation.
