I actually got lazy and just used my memoir assignment that I did for my AP Comp class for my common app essay.
I feel like my laziness is probably taking over and since I am biased, I don’t really know if my memoir even fits well with any of the common app essays. My guess would be it would fit best #5 “Discuss an accomplishment or event, formal or informal, that marked your transition from childhood to adulthood within your culture, community, or family.” Though it could work well with the other essays to so having your opinion on which it would best fit would be greatly appreciated.
