The Union Public Service Commission (UPSC) is expected to release the NDA 2 2026 answer key on its official website, upsc.gov.in. The key is for the written NDA exam held on September 13 in pen-and-paper mode, including the Mathematics and General Ability Test papers.

The answer key allows candidates to cross-check their marked responses and estimate probable scores. Multiple outlets note that the exam includes a paper-wise structure with marking guidance, and that candidates use the official marking scheme to calculate their scores. One source specifically highlights that the written examination consists of Mathematics and General Ability Test papers totaling 900 marks, and that candidates may account for elements such as negative marking when estimating results. Another source reports that the answer key is expected to be made available shortly as a PDF, following UPSC’s standard release process.

While the timing and exact document format are framed as “soon” or “expected,” both reports point to the same purpose: providing an official reference to help candidates verify answers and compute their probable marks using the marking scheme.
