What to know about this cycle
- ✓Tentative means listed in the official annual calendar, not a prediction. UPSC states that notification dates, exam commencement and duration may change.
- ✓The annual calendar is a planning source. It does not replace the CSE notification for eligibility, application instructions or examination rules.
- ✓Build your study plan backwards from Prelims, keeping time for revision, CSAT practice and missed-question review. Adapt the workload to your available hours instead of relying on a fixed preparation-duration promise.
