This is a great idea for a thread! Kudos for starting it.
I am a writer and I go to great pains, when the audience warrants it, to write well. My MD School Personal Statement went through 8 revisions! A very dear friend, an attorney and now a Judge, helped me with my personal statement. I made sure to share it only with him b/c he knows how to write well, he celebrates my writing and knows me well, and he knew what I was attempting. If I had enjoined more than 1 person, that would have complicated matters immensely. So, keep your evaluators to a minimum.
I got accepted to more than 1 MD school, but I can't say it was because of my personal statement. But it obviously did not hurt. So write one not with the focus that it will be the silver bullet or your ticket into MD or DO school. Rather, keep your sites on a PS that won't sink your application. Let is buttress your overall application so that the Medical School Admissions Committee can sit back and be wowwed by the total package.
As a non-traditional student, you have ALOT you can write/share in your statement. Pick a very close friend whom you admire/respect, who is also a writer, and is willing to partner with you to compose your PS. If no one like that exists, use us.
Post your statement on the thread here (take out the pertinent personal stuff) and let us give you some input. I don't have the time to take submissions via email and correct, so I apologize for not offering that to you. But it seems like there a few writers on this thread who have already posted, so you might give it a shot.
This is a really great idea!
