In my country, the children starts school classes at 7:00AM or 7:30AM and finish around 3:00 - 4:00PM

That is from Mondays to Fridays.

me as a parent, if longer hours means my kids would have the opportunity to learn more at the same cost of the tuition fees. I'm for it.

From what I understood, its the travel time to and from school PLUS the early waking up of the kids are the reason for the complaint.

My apologies if anyone find my comment inappropriate.
