UPSC map practice & Geography Optional connection
For UPSC Prelims, pair the location with its state, neighbouring relief and relevant geographic process. For GS I and Geography Optional Indian geography revision, use a simple labelled sketch to explain the relationship rather than replacing the answer with place names. These are Pragnya-authored exercises, not official UPSC previous-year questions.
