Hi rsethi1,
When it comes to training for the GMAT, there are plenty of options to choose from - more than just the 2 that you named. 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.
Are you just starting out your studies?
What is your goal score?
When are you planning to apply to Business School?
GMAT assassins aren't born, they're made,
