Frequently Asked Questions — UPSC Prelims 2026 Revision
Is 30 days enough to revise for UPSC Prelims?
Yes, 30 days is sufficient for revision — if your foundation is already built. The 30-day plan works for consolidation and accuracy improvement, not for first-time learning. Start your main preparation at least 6–9 months before Prelims.
How many mock tests should I attempt before UPSC Prelims 2026?
Attempt at least 10–15 full mock tests before UPSC Prelims. The quality of analysis matters more than quantity — after every mock, spend equal time analysing your mistakes and understanding why you got questions wrong.
Which subject should I focus most on in the last 30 days?
Current Affairs deserves maximum attention in the final 30 days since it contributes 20–30 questions. After that, focus on History and Polity which are consistent high-weightage areas. Science and Environment can be revised quickly with notes.
Should I read newspapers daily during the 30-day revision phase?
Yes, but limit newspaper reading to 30–45 minutes daily during revision. Focus on editorials and current affairs summaries rather than full newspapers. Use compiled monthly current affairs instead of starting from scratch.
What is the typical UPSC Prelims GS Paper 1 cutoff?
The UPSC Prelims GS Paper 1 cutoff varies by year and category. For general category, it typically ranges from 85–110 marks (out of 200). In difficult years it can drop to 80; in easier years it can rise to 115+.
