IESO Astronomy Problems (2007-2013)














IESO, or International Earth Science Olympiad contains one section of terrestrial astronomy. In the previous years, some similar problems from IESO appeared in the National Astronomy Olympiad. In this collection, I've compiled all the astronomy problems from past IESOs. Hope this will be a useful resource for astronomy olympiad preparation.
