You asked the question before even applying, so given the responses, the results, while disappointing, are not surprising:
Your SAT is well below the 25th percentile for MIT. You’re international, which lowers your chances further. You need aid, which is an issue for UChicago and any need-aware university.
MIT has a 2% acceptance rate for internationals. Aside from exploring local options, hopefully you’re applying RD to universities with higher acceptance rates.
