Find a good school that you like that will fit your child.
Personally I'd go for a school that I like and more academically inclined - as long as the kids can handle it, it should be fine.
For those popular school, if the number of applicant (less than 1km) exceed the vacancy, they would hv to go through balloting, those within 2km will not have any chances for balloting, would hv to find another school (less than 1km) to ballot
