Hi lamolnar,
You mentioned an interest in a Kaplan Course, but I'm curious which type of Course you specifically want: live in-person, live online or guided Self-Study?
I'd also like to know a bit more about your goals/plans:
1) What is your goal score?
2) When are you planning to take the GMAT?
3) When are you planning to apply to Business School?
There are lots of different study options besides a Kaplan course and most GMAT Companies offer some type of free materials (practice problems, Trial Accounts, videos, etc.) that you can use to 'test out' a product before you buy it. We have a variety of those resources at out site (
www.empowergmat.com). I suggest that you take advantage of all of them then choose the one that best matches your personality, timeline and budget.
GMAT assassins aren't born, they're made,
Rich
