<p>If you want to go to either UPenn or Brown, you’re going to need to SHOW (not tell) them how devoted you are to your respective passions - a lot of which will shine through your extracurriculars. You don’t seem to provide a lot of details about the things you’ve done outside of listing your positions; I’d think a lot about all of the things you’ve done in these respective organizations and positions and make sure that those details are clearly mapped out before you enter your application process. People focus on SAT scores a lot, but if your EC credentials are strongly phrased and show dedication and passion (that being, you’ve committed to them for long hours and years AND you’ve shown your undying love for them/specific ones in your essays), a college ad com may ignore your SAT/ACT composite scores altogether.</p>
<p>BEST of luck to you.</p>
