haha, okay, so now we have it all figured out--if you want to go to SUNY Buffalo, then it might be a good idea to do AmeriCorps 😉
Anyway, if I could do it again, I would do AmeriCorps, but I don't know that I would do VISTA. The difference is that VISTAs do "indirect service"--which means write grants and recruit volunteers and run programs and stuff, but you rarely do work in the field. Other AmeriCorps members do more "direct" service, such as tutoring and teaching for example. VISTA also requires a 365-day committment, while other AmeriCorps programs have a minimum number of hours of service, which you can complete in 10+ months. That would be a real consideration if you're still looking for a job--unless your VISTA service started already or is starting on Monday (as many are), you would not finish in time for most med schools. You can of course quit, but then you lose the education award so it's not an ideal situation. In that case, you should definitely not do VISTA. Also, as Kazema mentioned, since AmeriCorps counts hours instead of days, logistical stuff surrounding interviews wouldn't be as messy.
