UPSC Prelims General Knowledge Questions

GK is a tough nut to crack for UPSC prelims because there is no beginning and no end.One should therefore try and prioritize areas from where questions are most likely to be asked. I am sharing with you what all I prepared for GK in these four years and I hope that it would at least give you a fair idea as to what one must read as part of GK preparation for prelims.I would be covering GK portion in several posts over a period of time and this is the first one in the series.

Now this list is by no means comprehensive,but the point in GS preparation for prelims is that if you will keep reading without discriminating important from less important,you will end up reading a lot but remembering very less.....which would be a recipe for disaster.One can look up the inventions and discoveries from Manorama Yearbook or any other source,but learn to discriminate.
