Query: 90% cr*p

I hope the author of this book didn't take his work too seriously; this is just a book for laughs as far I'm concerned. 95% of this book is useless and time-wasting. It should have been called "Hardly Working at College: The Idiot's guide to barely or not graduating at all". And I didn't by this book, I wouldn't be dumb enough to, I got it as a gag gift.
