Hahaha, better leave your queries be answered by St. Stephen's parents la. Im not a parent with St. Stephen. Im old girl of St. Stephen's Girls' College while my girl studying in St. Paul (HV).
I dare not comment the English standard of St. Stephen. I came from 私立英小 & at my old days with St. Stephen, I was at the lowest level in English lesson.
My life with St. Stephen was sweet, with lovely & caring teachers, no discrimination despite my poor family backgd.
