Hi uHCWB,
Your question assumes that you "need" flashcards, which may or may not be the case. If you're certain that you want flashcards though, then the process of creating your own flashcards adds an extra 'layer' of learning/familiarizing yourself with the information that you're looking to memorize - so you might find it more useful to create your own. Beyond this subject, 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 materials have you used?
3) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores)?
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?
GMAT assassins aren't born, they're made,
