Other than the typical post-bac program/work/continuing with volunteering explanations, would it be appropriate or beneficial to write about preparing for an application and interview for a prestigious scholarship on par with Rhodes/Gates-Cambridge/Fulbright, etc. Even though I got to the late stages of selection, I didn't win it but I spent a great deal of time preparing for it. It also allowed me to pursue and reflect on an area of passionate non-science related interest. Given that I didn't receive the scholarship, I don't want it to come across as though I am trying too hard to show off whatever achievements I can.
