Hey Vivek,
What were the results of your practice tests like? Did they vary greatly from your actual result? If so, we have an article dealing with what might have gone wrong on test day:

You might also consider going back and evaluating your practice tests. We have several free resources that help you use your practice test Assessment Reports to focus your studies:

When you say that you studied for 300 hours, what took up the bulk of your time and how were you studying? We usually recommend that you do the In-Action problems in the Strategy Guides and then apply those principles to the OG problems under timed conditions. Also, we don't recommend doing practice tests back to back. Like I said, you should really use your practice test results to determine your strengths and weaknesses and how to study.
I think with some determination and hard work you should be able to increase your score. If you're looking for a Manhattan GMAT prep program to help you do that, I might suggest private tutoring, since you've already gone through all of our materials on your own. One of our expert Instructors will be able to help you analyze your strengths and weaknesses and develop a study plan.
That said, a 9-session course may also be a good fit for you. The benefit of taking a 9-session course is that you'd get to go back through the course materials in a methodical manner, getting expert instruction every week in class and through one-on-one office hours time.
If you have any other questions about our prep options or advice on how to proceed with your studies, please don't hesitate to ask! Feel free to give us a call (212-721-7400 / 800-576-4628) or shoot us an email, too (
