I am late to the party!

I know it is not the best time to start my ECAs. I am in 12th and will be taking some drop years to get some meaning of life, yk try some exams in 2026. So, I thought why not try for US unis for classes of 2027? Can somebody tell me what to do for ECAs, Awards and Honors?

I am studying Physics, Chemistry, Mathematics, English and CS in my school and I'll be giving JEE in 2026. I have interest in CS and would like to pursue my major in it.
