To sum it up: 19 highschools in Indonesia, 100% of their last grade students failed national final exam (er, dunno what’s this should be in English).
Reason: incorrect/fake cheat (answer) sheet.
Good job to whoever made that cheat (answer) sheet.
My take: burn the schools together with all the staffs involved. Or perhaps just ban them from teaching or anything that involves school activities. The students, well, should just take another year. It’ll most likely just ended as ‘blame game’ though.
