@vexelpops If you still care about an answer for this question, then yes, they have class on Saturday. Or well, they did and sometimes still do. It was mandatory in the past, a lot of schools then offered optional classes on Saturdays when that stopped and it being optional wasn't really stopping pretty much most people from taking said option because that Asian schooling pressure is the real deal, and then there was a push to make it mandatory again that I don't know the result of or if the result is still a work in progress. I remember a thing about there being class on half the Saturdays of the month and none on the other half too, vaguely, not sure where to slot it in with the rest though. Could've just been part of the optional section, with schools only offering the classes 2 weeks every month? Dunno.
