My chances at MIT?

Scored 1450 in the new SAT.
118 TOEFL score.
97% marks consistently for he last two years (India).
Currently in last year of school.
Some Olympiad activity, not major.
ECs include acting, music, debate, tennis, MUNs, swimming, some unaffiliated research, event management, school magazine editor.
Also calculus us real strong. Not my jokes though, they’re cancerous.

MIT would be a pretty sizeable reach for you, imo. Their mean SAT score is around 1530 and, especially with international students, they are extremely competitive at 3.1% accepted.
