Hi TIMEBBA,
You're asking a rather specific question, but it's not perfectly clear if either of those options is actually what you 'need' right now. As such, it would help if you could provide a bit more information on how you've been studying and your goals:
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)?
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?
GMAT assassins aren't born, they're made,
