Hi maharsh,
I mentioned this in a prior post, but it bears repeating - 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 our 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.
With the EMPOWERgmat Course, after enrolling, you have a 24-hour free trial 'period' - meaning that you can cancel at any time during that first 24 hours and not be charged.
If you have any additional question, then you can feel free to contact me directly.
GMAT assassins aren't born, they're made,
Rich
