Hi cananalyst,
Score 'ranges' (especially at higher levels) can be rather vague - the advice that I would offer to someone scoring Q46 would differ significantly from the advice I would offer to someone scoring Q50. This is meant to say that if you want an accurate assessment of your GMAT skills, then you should take a new, FULL-LENGTH CAT and do so in a realistic fashion (take the FULL CAT - with the Essay and IR sections, take it away from your home, at the same time of day as when you'll take the Official GMAT, etc.). While the 6 Official GMAC CATs are best, any of the CATs from Kaplan,
MGMAT or Veritas are 'close enough' to the real thing to provide a realistic assessment (assuming that you take the CAT in the proper fashion).
Before I can offer you any additional advice, 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?
3) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores for each)?
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?
