Hi Jeli131,
You bring up a number of important questions. Right now, there's no way to know for sure what combination of study materials would be best for YOU - and you might find that once you've studied for some time and better-defined your particular 'needs', you'll end up adjusting your study plan (and including some new resources).
The logical next step would be for you to start your own post-thread (instead of piggy-backing on this one), so that we can define how you've been studying along with your timeframe and goals. If you can answer a few questions, I'll be happy to offer you the personal advice that you're looking for (and I'm sure that others will too). If you'd rather not publicly post that information, then you can feel free to PM me directly.
Studies:
1) How long have you studied?
2) What study materials have you used so far?
3) On what dates did you take EACH of your practice 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 and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
