Hi hudacse6,
Many Test Takers become too fixated on the 'implied level' of the questions that they're working on - instead of what really matters: defining WHY they're getting questions wrong and becoming more efficient at approaching the overall Exam. It's also worth noting that just because a 3rd party describes a question as "700 level" does not necessarily make it so.
I assume that you're interested in these questions because you want to score at a really high level on the GMAT, but 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) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far?
3) On what 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:
4) What is your overall 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,
