I basically just said you’re fine academically and based on EC’s. At this point, stick with your strengths (sudden diversifying will show that you may just be resume whoring). Do not change paths to impress an admissions committee. Do what you do well and enjoy it so that you have something to talk about in essays. As for the biology thing, what can also help if you just approach your college major with a more open mind. Just go on to Emory’s website and explore some of the academic opportunities (whether inside of or something beyond a department) and that way you can find what you may be interested in besides being a standard pre-health at a top university. Emory may definitely take you based on stats. You just want to avoid being the “boring high achiever that wants to get into a top university” in your essays. Just demonstrate that it actually offers you something more than just space and that you offer it more than a long resume.
