The question is: you want a more perfect set of scores or you want to successfully apply to those colleges? Put your efforts into the right moves- not retaking.
The ACT is great and the SAT is fine. Done. Now do you understand what matters in the rest of your app/supps? How holistic will review you and for what qualities? Do your ECs adequately reflect this interest in education and bio? Don’t get distracted by this pursuit of what you think are better scores.
