Query: poorly written test prep book

I am in the process of studying for the AFQOT. I bought this book instead of the other test-prep books because it was the most challenging (the other books are apparently much easier than the actual test). All in all, there doesn't appear to be any single good book for the AFOQT. This book has plenty of typos, poor or no explanations, and oddly worded questions. I am not even sure if the author took any officer candidate tests himself. Buy this book if you want practice with electrical mazes, spatial apperception, etc. Don't buy it if you are trying to learn something new to you.
