No ec's

I am an Indian who lives in a remote area in Saudi Arabia. Currently in 11th grade, my parents want me to stay here till 12th.
The thing is, I really love science, physics to be precise. And I do complete question papers of various international olympiads just for the fun of it even though I can’t participate.
My aim is to just learn and do my best, but K cannot help but get intimidated by the extracurriculars required.
No one from my school has even thought about applying to american colleges, but here I am, oblivious and trying to get into the top ones.
I have a decent sat score(1560) and I am going to give the subject tests too.

Are taking full advantage of https://www.edx.org/ ?

Yup, I love Edx. Regularly do various courses. Super fun!

American colleges understand that international students often don’t have the kind of EC opportunities that American students do. You can write about your accomplishments/interests outside the classroom in your essay.
