thanks for replying, Dillon
If you're in our class, you'll have an opportunity to get essays graded and get written feedback during the course (after class 6).
As Dillon said, you can also get essays graded by GMAT Write (the official essay grading 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
www.mba.com and search for GMAT Write.
