Just go to a neighbourhood school within walking distance of your HDB pigeon hole. That's what I did. Less stress for the kid to commute to school.
Anyway, the schoolkids of today are fucked. They spend too much time in school, often I see large groups of them leave school at 4pm or 5pm, virtually the same time schedule as the working hours of a 9-to-5 wage slave. Back in the day, you only stayed back that late in school if you were punished with detention or there was a special celebratory event.
