If you're looking to make contact with other students, I'd suggest posting in the Study Groups section.
We don't offer free help via email - only here on the forums. You can also call our offices to talk to someone over the phone (800.576.GMAT in the US and Canada).
If you would like to get help here, please let us know your study and score history (including all subscores). Let us know what you have done that you think does work and what you have done that really does not work for you.
Use the below to analyze your most recent MGMAT CAT(s):
http://www.manhattangmat.com/blog/index ... ice-tests/Figure out what you think your big weaknesses are based on that analysis, and suggest some ideas for how to deal with them. We'll tell you whether we agree and advise you further. (Note: do share an analysis with us, not just the raw data. Part of getting better is developing your ability to analyze your results - figure out what they mean and what you think you should do about them!)
