I am currently a junior targeting HYPSM, Cornell, Duke, Vanderbilt, and Chicago, in addition to several safeties. I am primarily concerned with improving my chances in any way possible for these top-tier universities in the next ~1 year. At this point, I am intending to major in physics. Could someone please give me feedback as to which areas of the application to improve in the time I have remaining?
I have always been a strong writer and am cautiously optimistic that essays will be a strength of mine.
I know there are a lot of “chance me” threads for seniors on this site but I am trying to do whatever is necessary to improve my app now, before it is “too late”
