Many colleges take local context into consideration: if no APs are offered, then they don’t expect applicants to have taken APs (as an example). If there are no academic competitions available where you are, they don’t expect you to have won any.
So that’s probably what you do. Find something you’re passionate about and pursue it - it doesn’t have to be related to your school at all. Volunteer, serve, do a community project. All of that is great.
