To master the geography section of the UPSC exam, aspirants should develop a thorough understanding of both physical and human geography. Start with NCERT books for basics before moving on to advanced reference books like those by GC Leong. Create concise notes for crucial topics and use maps and diagrams to visualize data better. Regularly practice past papers and answer-writing to enhance application skills. Discussing topics with peers can also provide different perspectives and reinforce knowledge comprehension.
