Also Asked Questions by Defence Aspirants

1. When will the official UPSC CDS 1 2026 answer key be released?

UPSC typically releases the official answer key only after the final results of the entire recruitment cycle (including SSB and Medicals) are declared. For immediate verification, aspirants rely on unofficial keys provided by coaching institutes within 2-4 hours of the exam.

2. What is the "sectional cut-off" for CDS 1 2026?

UPSC usually mandates a minimum of 20% marks in each paper. If you score high in two papers but get less than 20 marks in the third (out of 100), you will not qualify regardless of your total score.

3. Will there be different answer keys for Set A, B, C, and D?

The questions in all sets are identical; only the sequence/order is shuffled. You must ensure you match your responses against the specific set code (A, B, C, or D) printed on your question booklet to avoid incorrect calculation.

4. Can I challenge the unofficial answer keys released by coaching centers?

No, unofficial keys are for estimation only. If you find a discrepancy in the official UPSC key (once released), UPSC provides a specific window for representations through their "Online Question Paper Representation Portal."

5. Does negative marking apply to unattempted questions?

No. There is no penalty for questions left blank. It is always better to skip a question than to guess if you are unsure, as $1/3 of the marks are deducted for every wrong choice.

6. How long after the exam is the written result usually declared?

UPSC usually announces the written results within 45 to 60 days of the exam date. For the April 12 exam, expect the results by late May or early June 2026.

7. Where can I download the official answer key PDF?
