Science High School student from the Philippines

I’m a dual citizen currently in the Ph with approx. a 3.7 gpa. Our school doesn’t offer ap classes but I’m in a science high school, which generally means we took entrance exams and we’re the country’s top students with higher level/ more rigorous classes and higher standards. Should I mention this somewhere? Should I include it in the portion of the common app that asks if I want to say anything that will help them understand my application better? Thanks!

No. Your guidance counselor can speak about the HS.
