Decent enough educational system for children needing foundation
educations. Safe enough for kids if you borther to keep them
educated and well train and discipline.

and studying for tertiary educations away from Singapore.

Only good thing about Singapore, its convenience at getting medical
services, food, shopping, travel & safety issues.
