Query: Boring!!

I've never fall asleep reading a book. I fell asleep ready this book twise. BORING!!It sure is wordy and waistful. I am an average "A-" student and usually don't critize any book but this one I felt that I waisted my money. Content is disorganized. WORDY. This book makes me hate dentistry because of so much garbage is in it, not enough content...Don't buy this one, you'll regred.
