Ok. Here is a list of the books i have:MGMAT Series (8 books): Definitely great, especially Math + SC
1-Veritas Series (15 books): Excellent Practice Material
2-Chili Hot GMAT by Brandon Royal: Never heard of it
3-Ace the GMAT by Brandon Royal: Never heard of it
4-The 3 official guides (both the 12th and 11th edition): Definitely great, again. Retired questions. Excellent practice.
5-Princeton Review 2009 : Maybe the AWA Section, but not that great. Just tips and tricks. Maybe additional practice.
6-Project GMAT Advanced Math (Veritas): Haven't used it personally.
7-Kaplan GMAT Premier Program 2009: See above.
8-Kaplan GMAT 800: I hear its pretty decent.
9-CR Bible: EXCELLENT book.
10-SC Bible : Use MGMAT instead.
11-LSAT RC Bible: Definitely worth having.
12-Doing Grammar by Max Morenberg
I agree with Whiplash ...
Pre-GMAT - Doing Grammar
Basics - MGMAT Quant + SC, Powerscore CR
, LSAT RC
Practice - Veritas books
, All OGs and Kaplan
books - maybe Princeton
Brandon Royal books - have never heard of them - After you have exhausted all sources, you can consider this for practice.
I understand that Project GMAT
advanced Math used to be the goto source for Probability and Statistics, this should be covered adequately in the new Veritas
guide.. you could always consider this for additional practice
