The city's school-aged children are expected to miss about 13 weeks of classes due to government-mandated shutdowns, first because of anti-government protests, now for the coronavirus outbreak. On top of that are the fees; tuition in one of the world's most expensive cities can cost upward of $20,000 a year.
