You have a great chance of getting into some of your schools. Even most of them. Clearly all the boxes have been ticked off. So look up what the chances are for those schools and thst’s what your chances are. You are an excellent candidate as most of HPY et al applicants are. In fact, several years ago? You might have stood out, but now your the research paper , has become a line entry for many privileged kids applying to top schools. A lot of these activities were things that made a person stand out until they became part of what one does to get into a selective school of one has the parents to facilitate. Nothing on your entire list that stands out. Nothing that Harvard needs—do they have a NCAA Tae Kwon Do team? Do they need another pianist? A violinist ?
Back some years ago, a friend’s son with nearly the exact resume as yours got into Harvard EA with almost the same resume right down to the TseKwon Do. He was the first crop of kids that authored research papers and had these activities that are now commonplace and de rigueur for high achievers today. There are a number of such kids selected each year, and you may be one of them.
You have a good list of schools and you ll do well on most of the outcomes. The BS/Med and Harvard and Yale are very much reach.
