There's nothing quite like being able to discuss issues and network with other parents with children in the same school as yours. Individual Schools' Official Parent Support Groups are welcome to come in and help out the incoming groups of parents.
Good! Both are good schools so consider the travelling. Else consider moving near HPPS as there are lots of good Sec, and higher education schools
if you have such good cards, I rather you choose the one nearer to home.
from HPPS to TPY is a good 20 mins by car.
Taking school bus = your kid will wake up damn early.
You send and pick up the kid = you will need to make multiple trips (very tiring one)
There is no school chats. Each class will form their own class chat groups. On Orientation Day, you will meet the form teacher and the rest of the parents. You can form class chatgroups through that.
