Title: Not what I thought it would be.
Review: Maybe I didn't properly read what the book was about, maybe i did. But this book was quite useless. I purchased it as an aide to better understand the concepts in my precalculus text. However, I learned it was nothing more, whatsoever, than what its title states: an outline. The book is better suited for people who already have a strong grasp of the material but would like a quick reference, more than for those who need extra help in understanding concepts. If you need clarity from your current school text and more guidance, I suggest you find another book. If you need a quick, very brief reference that explains very little, than buy this book. I erased it from my Kindle library and found better instruction on youtube.
