Summary
The CDS 2 Answer Key 2026 is useful if you want to check how you performed before the written result comes out. The exam is scheduled for 13 September 2026, and candidates may see different answer keys at different stages after the exam.
The first set of keys are usually released by coaching institutes. These keys can give you a fairly quick idea of your Score, although there can be differences between the answer key and different institutes. The official UPSC key is the one that matters in the end.
Here’s how the answer key works, where you can find it, how to raise an objection if a provisional key is released, and how to calculate your marks with negative marking.
1. Three Types of Answer Keys, and Which to Trust
| Type | When | Reliability |
| Unofficial keys by coaching institutes | Within hours of the exam | Useful but occasionally wrong |
| Official provisional key by UPSC | A few days after the exam | Authoritative, open to challenge |
| Official final key by UPSC | After the result stage | Final and binding |
Unofficial keys give you an estimated score on the same evening, treat them as estimates since institutes occasionally differ on the same question, with corrections appearing across the following days.
2. Expected Timeline for CDS 2 2026
Assuming CDS 2 2026 follows the same pattern to CDS 1 2026, the schedule would appear as follows –
| Event | CDS 1 2026 (Benchmark) | CDS 2 2026 |
| Exam date | 12 April 2026 | 13 September 2026 |
| Unofficial keys | Same evening | Same evening |
| Provisional key and response sheet | Around 16 April 2026 | Around 18 September 2026 |
| Objection window | 18 to 22 April 2026 | Around 5-6 days after release of Provisional key and response sheet |
| Final key | After the result stage | Later in the cycle |

4. How to Raise an Objection?
After UPSC opens a challenge window for this cycle, objections are accepted only through the official online portal at upsconline.nic.in, under representations on question papers and provisional answer keys.
The window for CDS 1 2026 stayed open for five days and Submissions of objections were accepted only through the online portal. Objections by email, post or phone are not accepted Support each challenge with a credible source reference UPSC does not reply individually to representations.
You should submit the objections within the window, since late objections are not considered.
5. How to Calculate Your Score?
The marking scheme is straightforward, but candidates frequently get the arithmetic wrong in their own favour. Add one mark for every correct answer, deduct one-third of a mark for every wrong answer. Count nothing for questions left blank.
English and General Knowledge each carry 120 questions, which are scaled to 100, while Mathematics carries 100 for 100. Calculate each paper separately since UPSC generally requires a minimum of 20 percent in every paper regardless of your total.
Once you have a figure, compare it against our CDS 2 Expected Cut Off 2026 bands and the CDS 2 Safe Score 2026targets to see where you stand.
6. Before You Panic About Your Score
Unofficial keys change, questions get dropped, answers get revised after objections and two institutes often disagree on the same item. A score calculated on exam night is an estimate with a margin of several marks either way.
If you are close to the expected band, begin SSB preparation rather than waiting. The gap between the written exam and the interview is long, and preparation started now is not wasted either way. Our CDS 2 exam analysis covers how this paper compared with April.
