Hi Betterthantherest,

There are some things that you can do to find a Course that best fits your personality.

First, take a FULL-length practice CAT. There are 2 that you can get for FREE from mba.com or you can find a free marketing CAT through a Google search of GMAT Prep Providers. Once you have that score result, you'll have a better sense for your strengths and weaknesses. You're probably going to be upset by that first score; don't worry about it though - it just establishes your 'starting' ability.

You should do a bit of research to sample the various GMAT Course options available. Most GMAT Companies offer free trials or practice materials so that you can get a sense of the material that you're about to purchase. You should test out as many as seem appropriate and choose the one that best fits your personality, budget and timeline.

GMAT assassins aren't born, they're made,
