Query: Unnecessarily wordy

This book is definitely not designed with a novice in mind. I felt that some concepts and explanations went round and round, never really explaining what was meant. It made for difficult reading. Unfortunately, i had to use this book for class, but i can say that at least 1/2 the class felt similarly about the book. I wouldn't buy it unless you had to. Plenty of other books out there with quality code examples to grasp the concepts better.
