Hi, all!
Just an FYI that instructors don't grade or give feedback on essays (see the forum guidelines for details).
But you can certainly post essays and hope that other community members respond.
Finally, you can get essays graded by GMAT Write (the official essay Also service from the makers of the exam) - they'll both grade the essays and provide feedback as to how to improve (for a fee). For details and pricing, go to http://www.mba.com and search for GMAT Write.
If you're enrolled in one of our classes, you'll get a one-time code to use GMAT Write for free.
