How to Calculate CDS Score
Candidates can estimate their marks by comparing their answers with the answer key and applying the marking scheme given in the official examination instructions.
A basic calculation can be made using:
Estimated Score = Marks for Correct Answers − Negative Marks for Incorrect Answers
| Response | Score Impact |
| Correct Answer | Marks awarded according to the paper |
| Incorrect Answer | Negative marking applies |
| Unattempted Question | No marks |
| Multiple Responses | Treated according to UPSC examination rules |
Candidates should use the exact marking scheme applicable to their CDS examination while calculating their score.
CDS 2026 Answer Key and Expected Cut Off
The answer key can help candidates estimate their performance, but it cannot confirm qualification.
| Factor | Why It Matters |
| Estimated Score | Shows probable performance |
| Previous Cut Off | Helps compare performance |
| Paper Difficulty | Can affect expected cut-off |
| Number of Vacancies | Influences competition |
| Candidate Performance | Affects overall score trends |
The official cut-off released by UPSC should be treated as the final benchmark.
