I know they've been posted before, but here is a simple question about: 3B. Tell us about a difficult or challenging situation that you have encountered and how you dealt with it. In your response, identify both the coping skills that you called upon to resolve the dilemma, and the support person(s) from whom you sought advice. I know they say they don't have preconceived answers, but I do have a challenge that I faced with my research. It took me over 6 months to get my project to work. We repeated step after step with minor changes until finally we replaced a secondary antibody. (Worked like a charm after that). Think research challenges is fine to use for that essay? I'd like to write about something that was a little bigger challenge than this, but I guess I can make it like a problem solving challenge type of thing. The way they word the question is like they are asking for something a little more serious than months of research down the drain. I know their next essay is about how you are a great fit for Pritzker (Essentially that you like research).
