I have been studying GMAT from past 2 months. In my diagnostic test (GMAT Prep 1 , from the software downloaded from mba.com) I scored 560 . Then I started with MGMAT books
for quant . Studied manhattenSC and then CR bible . Read all the book once and solved OG 12
and Quant and Verbal Reviev. Yesterday I have given Gmat Prep 2, my score is 550 again (v 20 and Q 47) , I am devastated. My exam is just 40 days from now. I am not getting what to do. One of my friend had suggested me to buy "Cracking the GMAT"
Should I buy this book now. Or its too late. I have left with 40 days exactly.
