I can only speak for myself.. I put my kids in rmkg is for what I like the kids to be doing.. music, mandarin, English, community activities, fun learning but academically solid and decent teaching and peers for my kids.. primary school placement come naturally after a kid is paced in a suitable environment .. sports training is not enough from my perspective and purely because It doesn't have outdoor playing field or swim pool, though school is linked up with external bodies to build its sports training approach.. this is not hard to supplement at home...
