Query: One of the most difficult books to learn from in existence

This book managed to turn a fundemental area of study into one of the most difficult to understand courses that I have ever taken. There is simply no transition from BASIC concepts to ADVANCED concepts. It was like trying to solve a triple integral, using knowledge learnd in kindergarden. I would advise against buying this book. Or better yet, i'll sell you mine!
