Ho i can get financial services by Columbia university, in order to cover the contract in the around of 51.890

I am 15 years old. And my English level is b1 . So , in my family or even in my country/ side almost no one got into IVY league :sob:. So i want to do that , and my one of the important dream it’s get into Columbia university. And i know that contract is 51.890 )))
So i need help by students, who have done this university or adult person , maybe teacher .
The thing is that i can’t pay 51.890 dollars ( it is so expensive for me ) but also everyone say that you can get financial help by C.Y Where i got 6.000 dollars, but anyway i can’t pay money around of 45.890 . Would be great if i was rich, but honestly it’s not.
So therefore, I need a person who can solve this problem (perhaps some of you have encountered such a problem) the fact is that I really want to go to Columbia University, and why are the talented guys always left unnoticed and one of the problems is money
