phtthp:Reach home around 6.40 pm is possible -
if we're talking about existing location, from hillcrest.
But from mount Sinai (2014 and 2015) -
earliest time to reach your house around duchess avenue, is around 7 pm.
6.30 pm - is school dismissal time.
The fleet of long school buses plus all the mini van(s) school buses to remote areas - must leave the school compound by 6.45 pm, thereabout.
Hopefully, all the p1 and p2 students co-operate well, can hop onto their school bus, punctually & correctly. not hop onto the wrong school bus number. This happened before.
every school bus bears a number.
if there is any delay, school bus can't leave by 6.45 pm; searching for missing student(s) on board. Then All the private cars queuing behind, waiting to fetch their daughters home, will also be held up. Because that road from mount Sinai leading out to the main holland road, is very narrow. Vehicles have to move out slowly in sequence, like a snail one by one, to main holland road.
Besides, around 6.30 pm -
P1 and p2 pupils from Henry park primary (hpps) very nearby, also going home, same time. There will be traffic congestion from these 2 schools, exiting towards holland road.
Hpps 2014 (p1 and p2) pupils also studying afternoon session, same as our p1 and p2.
Then once cars move out onto holland road, because is peak hour, the expressway also got traffic jam.
Btw, did you ask your driver whether your school bus is big one or is it a small mini van ?
Henry park should be single session, no more 6.30 dismissal.
