Is it better to have your 3 "most important" experiences all reflected in your personal statement? I'm describing a particularly vivid memory I have from doing research in an ER for a class in my opening paragraph, but I don't really consider the research class and experience as a whole to be a "Top 3" experience. Of the 8 or 9 experiences I'm listing it's closer to the bottom of the list, but I did learn a lot and saw a lot of cool things during the one semester I did it.
