One of the schools I'm applying to wants an additional essay/"explanation" (it's vague) because I'm a first generation college student. However, I don't feel that being first generation has prevented me from things, or been an obstacle I've overcome, or defined my education so far and I feel like I've been very fortunate to attend college and be applying to medical school. I guess my question is what to even write for this at all. A lot of my application centers around teaching/mentoring including at low income schools, do I tie this in? Everything seems kind of silly because I don't want to sound as if I'm using it as some huge obstacle I've overcome. Any insight would be very appreciated, sorry this was vague.
