Canadian students wanna go to Yale

Hello everyone
I’m a student who study in Winnipeg,Manitoba now and just confuse how can I go the the university in the US
I come from China and now I’m a permenant residence of Canada, study in a public high school now in Grade 10, I’ve got academic excellence in Grade 9 and plan to get more in the next 3 years.
What should I do to prepare for the Yale
I have a peer tutoring as my volunteer job and I know it’s not enough at all.So I’m trying to find more,I also take drama and wanna do culture exchange.
My school mark in 90 in Grade 9 and for sure I’ll take SAT next year .
Can anyone give me some suggestions about how to do more?

Get a 97+ the rest of high school and a 1500+ on the SAT and you will have a 5% chance of being admitted like most everyone else.
