Hi sahilmshah92,
Since you've already worked through 2 recent OGs, there's some question as to how valuable working through another one would be (especially if you're using the same approaches over and over but not seeing a bit score improvement). Thus, before you go that route, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied?
2) What materials have you used?
3) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores)?
Goals:
4) What is your goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
