Honestly, before I started this application cycle, I thought being unique was key, but now that I am almost through with it, I have completely changed my opinion. You don't need to be unique, you just have to jump through every hoop that's laid out for you, if you had volunteering, clinical experience, good GPA, MCAT, and research. You are set. If you are particularly good at one or more of these, then all the better. But unique things, barring the extremes such as refugee, war, olympic atheletic, and Lincoln Center solo experiences, are not gonna make a difference. Where you volunteer, what research topic you did, who you are as a person, don't really make a difference. Before I started interviewing, I always thought it was soo stupid when people are like, you shouldn't say you want to help people as a major reason to why you want to become a doctor, because, heck, if I were a patient, a doctor's compassion is perhaps the foremost thing on my mind. Anyway, but it turns out that you don't have to be that unique, just do the standard things and you will be fine. If you really want to be unique, then get a 42 on the MCAT.
