Query: This book is really difficult for new Calculus students!

James Stewart has gone far and beyond from the ordinary math course. He uses good examples and excellent looking graphics. However, once you start doing the problems they soon become quite difficult after doing four or five of them. I have spoken to a different Calculus instructor, not mine, and he says the same thing. He said that the author did not publish enough simple, easy to do problems before immediately getting into real difficult problems. I give it 2 stars because it might be easy for a math major to understand this text, however this book is supposed to gear more towards first time Calculus students.
