Hi Shaheensingh17,
From your post, it's not clear whether what you 'want' and what you actually 'need' are the same thing. It's unlikely that "700 level" Quant questions are actually why you have not hit your score goal yet, so focusing on those types of questions will probably not get you to your score goal. Before I can offer you the specific advice that you’re looking for, 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,
