Hi Varsha,
You posted this message in another Forum on this site, so I've copied over my response from there:
You have not provided any information on your studies, practice scores, etc., so it's not clear whether you actually need to be focusing on "700+ level" questions or not. As such, 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 apply to Business School?
6) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
