Ok practice tests: I was scoring 730-770 on the two official GMAT tests, but the old ones.
On the
Manhattan GMAT ones, I was scoring much less...but they are very tough on purpose
For RC, you have to do so many questions that you actually get to understand how the people who write them think and the answer they would like to see. I used a simple elimination process.
To be hones,t I have always been good with languages and had a good intuition of grammar rules. I only practiced with the hardest questions (again, thank you
MGMAT). Remember, I scored a V43 even the first time around
For me, the gain was really 1) the very hardest verbal questions and 2) the math -- getting quicker and memorize set ways to do the problems, espec probabilities which come up at the 45+ score level.
Hope it helps
