1. Don’t expect that there will be school all that often.
Argentina has more national holidays than any other country on Earth. And for every one of them, school closes. We’re not talking just Easter and Christmas here — for example, there was no school this week because we were honoring the day some General from way back ‘passed over into immortality’. There’s lots of Generals, and we celebrate their birthday, their death, the day they started second grade, the birth of each of their children, the death of each of their neighbors… Okay, so I’m exaggerating. But not by much.
And if a holiday falls on a Thursday or a Tuesday, you often get Friday or Monday off too, just for good measure.
