Hi Ali,
Your profile shows two 430 Scores - and if those are relatively recent Official Scores, then you shouldn't be focusing on '700 level' questions right now. 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 study materials have you used so far?
3) Are those two Scores Official Scores? If they are, then on what dates did you take the GMAT? Have you taken the Official GMAT any other times?
4) How have you scored on EACH of your CATs over the last month (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
5) What is your goal score?
6) When are you planning to take the GMAT?
7) When are you planning to apply to Business School?
8) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
