I agree with @ap012199 . I think that Georgetown and Brown are your only true reaches. I’d send your ACT as it is better than your SAT. Make sure to narrow down that list of activities to your most important 10. Perhaps think about retaking the ACT in the fall if you have a chance to and/or apply ED to Brown/Georgetown if they are your first picks.
