Out of curiosity, why Georgetown? It’s known for many things, but not really CS.
I mean, your list of schools is obviously well thought out, so you must have specific reasons for Georgetown.
Regarding overseas, why Oxford and not Cambridge or UCL? Just curious - all are excellent, and there are no bad choices there. Also, why not ETH or EPFL in Switzerland?
As for your chances, I’m not as bullish as @DadOfJerseyGirl, but I do think that you will be accepted to at least three of NEU, Michigan, UIUC, GTech, and UCSD. Purdue and Rutgers are yes, as are UTD, TAMU, and UNT.
I like your chances for Oxford, IF you get 5 on Calc BC and/or AP Physics II. Otherwise, you may not qualify (you need 4 5s or 3 5s and an ACT of 33 OR an SAT of 1480, so you need one more 5)
