Getting into a Top 20 school will depend on more than just your GMAT and GPA. They are good places to start, but of course a LOT will depend on your ESSAYS. You will need to do what you can to show your PASSION, to show you are DIFFERENT. To interest and excite the AdCom. That is what will make the difference for you. If you can do that, you should have preeeeeetty sweet chances with a good strategy.
