Well, what worked for me was finding something unique about each program that related to my goals and desires. I made sure to emphasize points that I had not really elaborated on in my initial aacomas app. It would be a wise choice to give the ad comms as much info about yourself as possible. Find something that your passionate about that you have not already described, and relay that passion in your essays. Ad comms know that you want to pursue osteopathic medicine... now let them know why you chose their program above all others.
IMO, it is more professional to type your responses. When I applied, I composed my statements in Word, printed them, pasted them onto the application itself, and then had Kinkos copy them onto paper that matched the originals. I'm sure that there is a less complicated method to get the same results- perhaps using a scanner or something of the like. Hope some of this helps.
