Query: Awful!

I would never recommend this as your primary study aid, maybe as back-up to help with the harder math questions. But if you use this as your primary aid, if will intimidate and only make your feel like a loser.BUY THE CLIFF NOTE VERSION!!!! The CN version explains everything step by step whereas I felt this version was way too unorganized and scrambled.Wish me luck because I take the test Thursday!
