While in college, I was involved with the IITG amateur astronomy club. While I barely know my way around the night sky without a sky chart (thanks to having grown up in a city), I did help with organizing some competitions — mostly with framing (hopefully interesting) questions. Here are two problem sets, from
2009, and from
2010. There was also a “
