Frequently asked questions

When is the UPSC Prelims 2026 exam being held?
The UPSC Civil Services Preliminary Examination 2026 is scheduled for 24 May 2026. Paper 1 (General Studies) runs 09:30 to 11:30 IST and Paper 2 (CSAT) runs 14:30 to 16:30 IST.
When will the UPSC Prelims 2026 answer key be released?
Dalvoy publishes the answer key for both papers within an hour of each paper ending — GS Paper 1 by 12:30 IST, CSAT by 17:30 IST. UPSC itself releases the official provisional answer key two to three weeks later, and the final key only after the results.
Are Set A, B, C and D answer keys different?
No. The question paper content is identical across the four sets — UPSC only shuffles the order of questions. Pick your set in the answer-key controls above and the table reorders to match the paper you wrote.
How is the UPSC Prelims 2026 score calculated?
Each correct GS Paper 1 answer is worth 2 marks. Each wrong answer deducts 0.66 marks (one-third). Unattempted questions carry no penalty. Use the score calculator above to estimate your total.
What is the expected cutoff for UPSC Prelims 2026?
Based on the trailing 5-year average and current difficulty signals, the General category cutoff for 2026 is expected to land in the 80–90 band. The expected-cutoff table above breaks this down by category and will be refined once the paper has been fully analysed.
How can I challenge an answer in the official UPSC answer key?
After the official provisional key drops on the UPSC website, you can submit objections through their grievance portal within the stipulated window — typically 7 days. Include the question paper set, question number and supporting references.
Is CSAT counted towards the Prelims cutoff?
No. CSAT (Paper 2) is qualifying only — you must score 33% (66 of 200 marks) to qualify, but the cutoff for moving to Mains is decided entirely by GS Paper 1 marks.
Where can I practice UPSC PYQs after the exam?
Use our Previous Years archive (linked below) for question-wise practice with detailed solutions, subject tagging, and topic-wise analytics across every year since 1995.
