Query: Not an easy read

I had to read this book for a statistics course. In the Preface, it states "We presume students using this book have a minimal mathematical background (high school algebra) and no prior coursework in statistics" (page xi; 2004 edition). I found this statement to be stretching the truth; this book is hard to read, hard to understand and hard to digest. Contrary to the preface's inviting statement, the reader would be in a MUCH better position to have mastered calculus and to have HAD previous experience in statistics. This book is NOT an easy read as the statement above would suggest. I had to abandon using this book in the course and resort to other texts. Caveat emptor.
