I am a sophomore at an ivy league school, I have a 3.8 GPA (both science and regular), volunteer experience, research, tutorring little kids, very good references, etc. Havent taken the MCATs yet, but I plan on working my A$$ off to do whatever is necessary to get a competitive score. I am not really concerned about getting into medical school, but rather I very much would like to get into one of the top 10 schools - perhaps columbia or UCSF. What else do I need to be doing? Distinguish myself somehow? But how? Would going to a 3rd world country for a summer to show humanitarianism be good? How about becoming an EMT? Taking a leadership position in an activity at my college? What are some things that you have done, or have heard of others doing, that you think are really impressive? Thank you very much for your input.
