I would recommend this book for someone who has already been through Algebra, Linear Algebra, and Geometry and don't need explanations for anything but want some problem practice. Even then I hope that they have some inkling as to HOW to solve these problems because even though they are solved, the author only gives you the bare minimum of the steps.
It is not a book to be used on its own at all, however if you want to have easy access to the formulas and stuff like that this is a great reference to have.
