UPSC National Defence Academy and Combined Defence Services exams were held on September 13, 2026. Candidates woke today searching answer keys, cut-offs and next dates. This guide compiles credible unofficial keys, safe score methods, realistic ranges, and the usual result window. Use it to estimate chances and calm uncertainty.
Both papers had multiple sets, typically A to D, with identical difficulty. Unofficial answer keys now circulate for Mathematics and General Ability Test (GAT) in NDA. And for CDS, they cover English, General Knowledge and Mathematics. Treat them as provisional. Cross-check at least two reputable analyses before finalising responses and score estimates.

For NDA Mathematics, award 2.5 per correct and deduct 0.83 per wrong. For NDA GAT, award 4 per correct and deduct 1.33 per wrong. For CDS English and General Knowledge, allot 0.83 per correct and deduct 0.27 per wrong. For CDS Mathematics, allot 1 mark per correct and deduct 0.33 per wrong.
Past cycles place the NDA written cut-off near 340 to 360 out of 900. With comparable difficulty, a prudent band is 360 to 380. For CDS, recent aggregates often read IMA 120–130, INA 110–120, AFA 140–150, OTA 90–100. They sit alongside the typical 20 percent minimum in each paper.
| Exam/Academy | Past written band | Safe range now |
|---|---|---|
| NDA (out of 900) | 340–360 | 360–380 |
| CDS IMA (out of 300) | 120–130 | 125–135 |
| CDS INA (out of 300) | 110–120 | 115–125 |
| CDS AFA (out of 300) | 140–150 | 145–155 |
| CDS OTA (out of 200) | 90–100 | 95–105 |
UPSC usually publishes the written result within four to six weeks of the exam. For a September 13 test, expect a list of roll numbers by mid to late October. Official answer keys arrive much later, often after the final selection stages conclude. Track the commission website and keep your admit card handy.
Register or update profiles on service portals after results, then await Service Selection Board (SSB) call-ups. Organise Class 10 and 12 marksheets, graduation certificates for CDS, photo identity, and category or NCC proofs. Start light physical training, revise current affairs, and practise psych tests, group tasks, and interview basics.
Average scores from two credible keys, recalc with negative marking, then compare with the safe bands. If close, continue SSB preparation without pause. If short, audit topics and plan the next attempt. Either way, secure documents now and keep checking for the written result window.
