I would say the most helpful part of the process was the essay help I received. When I started writing my essays, I was not sure of what would be appropriate to include (especially for the direct med programs). For example, I remember one tip you gave me for the common app essay was to stay clear of listing off the extracurricular activities, since that information would be available to the admissions officers in another section.
The help and information I received both about essay writing and about interview preparation is instrumental to everyone, at some point, all students will go through this process.
The interview preparation was very helpful!
