GMAT Math Workout (Princeton Review Series)

Summary: Good at explaining some concept but full of errors!
Review: While the book was good explaining many concepts and refreshing me, I had a hard time since it was full of typos. I have been out of college for a while and bought this book just to refresh myself on mathematical concepts. I've always had a very strong grasp on mathematics and just needed to glance over some concepts. I found the book good at explaining many concepts, but the reason I felt compelled to write a review is because there are numerous critical errors in the book. For example, in laying out a basic rule for students to memorize, the book mistakenly writes that an Odd X Odd = Even. There are also several instances where the answer provided does not match the answer's explanation. But an even bigger mistake in the book is where the author provides an incorrect answer and explains why it is correct. It was the wrong answer! I would definitely recommend that you use another source in addition to this book.
