I need to buy GMAT MATH BOOK to brush up my basic skills in details.
Can anyone plzzz provide suggestion as per which book can I buy?
Note: I am an average student in MATH.
Initially I have OG 11Edition.
Basics? I'm assuming you're not trying to get a 48+? If you're not and are targeting something in the 45-47 range, you should be ok with just a Kaplan
/PR book and the OG to practice with. Get the quant supplemental book as well.
I think mgmat is really for people who want to fully understand all the concepts and score highly 90th%ile+
