The reader of your medical school application is expecting a degree of proof and really wants to know how you know. It's not enough for you to say you want to help people. How do you know what you want to do in medicine, what have you done that leads you to know that? How to write your medical school personal statement: Persuasion The most persuasive way to answer this question is by sharing experiential knowledge. You would say to an admissions official in conversation, "I know because I've done it. That's how I know. And I can give a specific story."
You already know that your personal statement could be the one factor that keeps you out, or lets you into the school of your dreams, but you may not know how important it is to have a fresh set of eyes on it before you turn it in. While you may have read over your personal statement several times, there are still reasons that you will want someone else to read it over as well.
