Query: Completely revised my way of learning math from a book!

Ostebee and Zorn presented Calculus in a mind stimulating and reform way. No more copying examples out of the book because every problem is the same. This book makes you discover the methods and understanding. The basic understandings are provided, but the rest is up to you! I have never understood Calculus so thoroughly! I do not rate the book five stars, because of the unreliable solutions manual. The book is geared toward user discovery, so the solutions in the manual need to be CORRECT in order for the user to benefit the most.
