Hi atshy21saraf,
How long have you been studying for the GMAT?
What resources have you been using?
Since you have less than 2 weeks until your Official Test Date, and you have a defined score goal, I really need to know the specific answers to these questions before I can offer any advice:
When you took your CATs:
1) What was your score on each of your CATs (including the Quant and Verbal Scaled Scores)? What 'brand' of CATs did you take?
2) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
3) Did you take them at home?
4) Did you take them at the same time of day as your Official GMAT?
5) Did you ever do ANYTHING during your CATs that you couldn't do on Test Day (pause the CAT, skip sections, take longer breaks, etc.)?
GMAT assassins aren't born, they're made,
