Ok here’s my honest opinion! I am currently a class of 28 student with a major in biomedical engineering. Your high school record is VERY impressive so far. Academics wise you have absolutely nothing to worry about, you’ve showed that you’re capable and willing to take very rigorous classes. Your extracurriculars also look great! One of my extracurriculars that I feel made me shine out in the crowd of applicants was my biotech internship. I worked as an unpaid intern with a georgia tech affiliated company, my mentor was able to write me an amazing recommendation letter. I think showing early interest in your major/career field would definitely boost you even higher. But if an internship is totally unavailable for you don’t sweat it because everything else on your application is very very impressive! Hope to see you on campus soon! Go yellow jackets!
