So I think you’re on the right track so far in terms of where you should be at about the middle of 10th grade.
Other things you can do: scribing, blood donation drives, cancer drives, medical fundraising marathons, physician shadowing (private practice is probably easiest in terms of access), volunteering at senior citizen nursing homes, maybe volunteering at a place for those who are disabled, etc. A lot of these are relatively quick and short term.There are so many examples out there which you can find here on CC in terms of people’s CVs, when it comes to filling out an app. I was going based off the website for PLTW and their Youtube video and it seemed more Biomedical Engineer/Research -ish. If your ECs were weak, I’d say to do it, but they aren’t. You’re already participating in something similar in terms of Native OKstars and you’d be taking Human Anatomy and Physiology your junior year and the PLTW thing might just reproduce that aspect. You would already have so much to talk about in interviews with your other ECs in terms of formalized medical/research programs.
Besides maintaining your grades and class rank, which should be your #1 priority, work hard for either the SAT/ACT to get the highest score you can. You may need particular SAT subject exams depending on the particular program you’re interested in (i.e. Brown, Northwestern, etc.). By the end of Junior year or at least by the end of that summer after Junior year, you should be done with all standardized exams. You’ll be quite busy with apps during Fall of Senior Year so it might be a little difficult to still tackle those depending on how late you were to take it then.
Just FYI, if you decide to do UMKC’s program, even though you are regional, becase you are Native American, if accepted you would automatically get the Chancellor’s Nonresident Minority Scholarships to where you would pay in-state tuition for the Bachelor/MD program. Just something to think about.
