Hi anjalimathur1003,
You're actually closer to your score goal than you might realize. Each of these CAT scores shows that you're performing at a strong level in both the Quant and Verbal sections. At this scoring level though, the GMAT becomes really 'sensitive' to little mistakes, so you really have to "nitpick" your CATs to figure out what you're getting wrong and WHY.
To that end, here are some things to think about when you're reviewing a CAT:
After reviewing the section, how many questions did you get wrong....
1) Because of a silly/little mistake?
2) Because there was some math/grammar that you just didn't know how to do?
3) Because the question was too hard?
In the Verbal section, how often are you 'narrowing it down to 2 choices and "guessing wrong"?' If you're that close to getting the question correct, but you're still getting it wrong, then you have to work on that 'last step.'
Another thing to consider is how well your CATs match up to the reality of Test Day. If you're doing ANYTHING unrealistic (skipping sections, pausing the Test, taking the CAT at home, etc.), then your scores might not be perfectly accurate.
GMAT assassins aren't born, they're made,
