American citizen living abroad

I’m a sophomore in an Indian secondary school, however, I’m a citizen of the U.S. From what I’ve heard, my application will be considered with those of domestic applicants, but I don’t necessarily have the same opportunities as them and I don’t qualify as an international applicant.

For example, my school does not give grades for assignments (the only recorded grades are those from examinations which take place every other month), we don’t have a GPA system, and no AP/IB/Honors programs are offered. My grades are well above average for my grade, but they don’t look so good on paper (ranging from the low Bs to As, although some have been much lower than that).

I’ve already taken the PSAT and will be taking my SATs this year. I will also be taking a couple AP exams (I can only take one AP exam a year since I’m self-studying for them and have to balance schoolwork).

I haven’t done any volunteer work and haven’t participated in any extracurriculars since starting high school. Also, I haven’t really gotten any awards or done anything noteworthy yet.

Do I have a good chance of getting into a reputed college in the U.S.? Or am I at a major disadvantage? Will the rigor my courses in high school be taken into consideration? What can I do to increase my chances of being accepted into a good college?

Any suggestions would be appreciated. Thank you.

Probably not the right place to post this. I replied to your other thread.
