I bought this book to help me with my Pre-Calculus work and found it v ery helpful, however it does come up a bit short in comparison to what is included in most of today's precalculus textbooks. I would say that 75-85% of my textbook was included in this book. What was included in the book was extremely helpful as a last minute test review which reflected on my test scores.
