The pillar article explained why CSAT decides your Prelims. This part gives you the how — a calm, realistic 11-month roadmap that fits around GS, so Paper 2 is a finished task long before exam day. This month-wise study plan is Part 1 of the UPSCPDF CSAT 2027 Strategy Series. Before following the calendar, read the parent article to understand why CSAT is qualifying in format but decisive in outcome, how 66.67 marks work, and why Paper 2 needs year-round preparation. A good month-wise CSAT 2027 study plan is not about studying more — it is about starting earlier and spreading the work so thinly that Paper 2 never becomes a crisis. This guide runs from July 2026 to May 2027 and tells you exactly what to do each month, so CSAT stays a quiet parallel track and never steals time from GS Paper 1. In the pillar article, CSAT 2027 Strategy: Why UPSC Aspirants Must Stop Ignoring Paper 2, we made one argument clearly: CSAT (Paper II) is qualifying in format, but decisive in outcome.
