Ensure that your notes are short and up to the point. Cover the important aspects of the topic and present it with a suitable solution to the issue as it is asked to write 250 words in the UPSC exam. Also make it a point to use flow charts, pointers, mindmaps in the answers. Make the concepts clear to understand by the examiner.
