Nothing with dollars is involved. When starting school you will have take admission exam and pay admission fees of around 40k or so. After that every two months you pay (for 9th grade P-1) around 12k, give or take a few. O Level exam fees are around 5k per subject in (11th grade SR-II). Trust me there will be no compulsory extra curricular activities involved. Unless you want to go on field trip, which really don't take place now due to security reasons.
