Totally agree with kartikeya - lots of very smart people just don't do well naturally on these tests... but they can learn how! We just need to figure out why your score is where it is, that's all.
If you have been taking MGMAT tests, use this article to analyze your results:
http://www.beatthegmat.com/a/2009/09/23 ... tice-testsThen come back here and tell us what you found out. (If you haven't taken one of our tests, sign up for a free practice test so that you can do the above analysis. NOTE: if you haven't taken our test yet, make sure that you take the test under 100% official testing conditions, including the essays, the length of the breaks, etc. If you have any questions about official testing conditions, let us know.)
Also let us know how you have been studying so far. What materials have you been using? What do you do during a study session? How do you review your work? How do you learn from your mistakes? How do you determine what your weaknesses are and what to do about them? Etc.
