Extracurriculars for highly selective colleges

Hi

I'm Kartikey and I have a major concern about my extracurriculars. I'm already in grade 11 and I don't feel like I have any big spike that I can add to my college application. I'm from India and haven't had a lot of achievements except being one of the top students in class and winning a few olympiads at zonal level.

Please guide me for I highly need it.

Thanks
