Hi uditgopalka,
In prior posts (in both June and August), you noted similar CAT/mock Scores to the one that you posted in this thread - so it's possible that you have gotten 'stuck' in the 500s. If you have developed any 'bad habits' during your prior studies that are keeping you from scoring higher, then we will have to work to define those habits (and replace them with new 'good habits'). If your Score Goal is still 700+, then you will likely need at least another 2-3 months of consistent, guided study before you can consistently score at that higher level, so you might need to consider pushing back your planned Test Date.
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) Have you taken the Official GMAT yet? If you have, then how did you score?
2) What type of study routine have you been following over the last 5 months? How many hours do you typically study each week?
3) What study materials have you used so far?
4) On what dates (or approximate dates) did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
5) What is your overall goal score?
6) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
