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.

About Ky

Currently Indonesian university student trying to submit more useful contents to share one's limited knowledge. Rather has wide, shallow interests, the writings will be as sporadic as it can be. Should write more scientific and field related topics, but writing muse says otherwise. Expect more on technical related writings especially softwares and apps, cultures, music, and random things.
