As far as I know all additional curriculum(payable) is after class hours. For Sat (payable) one needs to register first.

Those children have learning difficulties are not encourage to study in sjkc, they are very adamant about result/ exam quota, which means these children must pick up learning to be same rank as general children or else, they have the right to kick the child out of school. Government school are more lenient towards exam result.

None Chinese edu parents that sent their child into sjkc needs to have addition work like join in the homework community which certain parents set it up so that they can discuss about thrir child's homework or work your butt off translating using Google to teach your child.

I'm saying all this based on my experience and yes...my son kena kick out for being mild autism.
