UPSC CSE · GS · CSAT · Essay
Subject Wise Preparation
One hub for the ten subjects FIRST IAS INSTITUTE uses to structure Prelims and Mains. Each page covers syllabus, PYQ themes (with links to official papers on this site), resources, strategy, common mistakes and an answer-writing or solved-approach example.
How to use this hub
Open a subject, map it to the official UPSC syllabus, then practise from the explained PYQ Archive (and the older PDF download tables). Strategy on each page follows the same pillars as the Ahuja Sir seminar: limited sources, writing, revision. Institute context: FIRST IAS Institute profile.
