Two of the popular curricula are the American curriculum and IB.

The American curriculum is especially for children who want to get into US-based universities. For that, this curriculum widely provides Advanced Placement (AP) classes, but the availability depends on particular high schools.

Along with theoretical exposure, the curriculum also emphasises participation in co-curricular activities. 

It involves a continuous assessment system based on GPA scoring, instead of completely relying on final exams.
