Yes, 4 years is an eternity at your age. 
(For adult posters: I always remember the end of Dead Poets Society - in the film, one year seems like a fine compromise to adults and simply impossible to bear to the teen. I remember watching the film as a teenager and reacting to the idea of one year as clearly impossible in the same way being a hostage and tortured for a year would seem unconscionable.)
@charann:
Have you run the NPC on ANY US college?
If so what colleges and what were the results?
(They will be inaccurate but will give us an idea)
I don’t understand why you wouldn’t be interested in Informatics, UX/UI, CS systems… If you’re interested in CS.
Are you willing to compromise on rank and specific major if it gets you to the US? Or not at all, CS or bust?
Have you looked into the European options I listed? At those your SAT would be considered high (because European systems focus on long form writing students there do quite poorly on multiple choice tests where no one cares how broad your reading or how elegant your reasoning is.)
