National/ International Astronomy Olympiad Problem Sheets
I have some of the files, but I think it’d be easier to link to their pages as well (so that if anyone asks me I can just link him/ her this). Basically, you can just go to their own respective websites, but having them in one place will help (and also, especially for my Indonesian students/ friends). I try to link to official websites if I can. If I don’t have the links but I have the files, will upload them.
(Still building sources from dusty folders)

If you want more, you can also check past OSN Kebumian (Indonesian Earth Science Olympiad, also in Bahasa Indonesia) papers, it has roughly 20% Astronomyrelated questions.) (syllabus) (note: by reading this part and the IESO part below, you can’t help but wonder why all Earth Science olympiad organisers are really nice in uploading their questions online)
