GRE/GMAT Math: A Systematic Approach;

If you have ever wished for a book that would equip you with the knowledge base to answer math questions on any topic pertaining to the GRE/GMAT, then this book could be your answer. A timeless edition, it is neither as boring nor as technical as a textbook; yet it lucidly explains every single math concept you may encounter on these tests. Moreover, it features over 500 solved examples as well as over 500 practice questions (with full solutions) to reinforce what you learn. The author recommends finishing this book before starting with full-length sample tests from various sources, and returning to it as needed.

Awarded the KIRKUS STAR by Kirkus Reviews, and a SILVER MEDAL at the 2014 Readers' Favorite® International Book Awards, this book does not focus primarily on short cuts. Nor is it written assuming anything about your level of preparedness. Once you understand the subject matter, short cuts will automatically occur to you. The book shows you how.

This book employs an easy-to-understand, conversational style text that native as well as non-native speakers of English would appreciate. It is so well-organized that there is a chance you might retain it as a general reference for math concepts.
