Query: Hated it.

This book was exceptionally watered-down. The practice tests are MUCH easier than the actual exam. When I took the exam, there were only two formulas provided on the formula sheet, and one was De Moivre's Theorem, which this book only devoted a paragraph to. The book made it seem as though many formulas would be provided with the test, which were not. Only rely on this book if you have to cram and want to fail.
