This was a service that I should have used in my first go, but either / or, it was a really good service that got me one admit from M7, and one from a T15. The feedback that the site provides for each school is so helpful. Its concise and it gives you great pointers on what to write, how to shape your essays so that it fits into what the ad-coms want and what to avoid. PLEASE, take my word, even though the advice is remote, not-specific to you, and not being given by a live consultant, it is better than what a traditional consultant would say, because it is so school-specific and so relevant to the essays.
Its a great resource, and though I didnt use any add-on features, I am sure those must be really great.
