So I'm starting to get back into the swing of things this semester and finding out that I have little to no time for some major XC's. I was just curious how many XC's people partake in outside of normal volunteering and research. Also, what does one mean by saying that they have "lot's" of XC's. Reading that, i picture a 20 page resume filled to the brim with all the goodstuff medical schools want from applicants. Any info?
