Hi samkvc15,
When it comes to studying for the GMAT, there are a variety of different options. 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 website (
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.
If you have any additional question, then just let me know.
GMAT assassins aren't born, they're made,
