I am glad so see another pre-med like me. I am in a similar situation as OP, I am 17 yo senior, got into biggest state univ at 13, will graduate with chemistry and biology before turning 18, honors research with thesis, current 4.0 gpa, mcat 37. I had been living on my own since 14, and got emancipated by the court the week I turned 16, so I could go on foreign medical mission trip and work full time during summer at a childrens hospital.
From the limited feedback I have received, I think my age will not matter because I have been independent for years. I guess I will find out soon since I am starting to do my secondaries.
