Aspirants Challenge 27 Questions in UPSC Prelims 2026 Answer Key Before CAT

For many young Indians preparing for the Civil Services, the preliminary examination is the first and often the toughest filter. This year, that filter itself has come under close scrutiny. At least 27 questions from the 2026 Civil Services Examination Prelims, spanning both the General Studies and aptitude papers, are now under dispute. Candidates argue that the answers given in the UPSC’s provisional answer key are either wrong, have no correct option, or leave room for more than one valid response. Two separate groups of aspirants have taken the matter to the Central Administrative Tribunal. One group of four candidates has challenged eight questions. A larger group of 63 aspirants has challenged all 27, which includes those eight. On 9 September the tribunal issued a notice to the UPSC. Both cases are scheduled to be heard together on 8 October. The preliminary examination was conducted on 24 May. The provisional answer key appeared three days later. Results followed in June, and the Mains examination took place in August. Several of the petitioners say they missed the cut-off by a very small margin. In an exam where negative marking is the norm and the final qualifying score is often decided by just a few marks, even one or two disputed questions can change the outcome of an entire year of preparation. Among the questions raised by candidates is one on Grand Slam tennis tournaments. They contend that the official answer overlooks a ranking threshold clearly stated in the tournaments’ own rules. Another question concerns the Zero FIR provision under the Bharatiya Nagarik Suraksha Sanhita, 2023. Aspirants point out that the Hindi and English versions of the paper use different language, one closer to “investigation” and the other to “preliminary inquiry,” which could lead candidates to different conclusions depending on the language they read. Several questions related to the Rigvedic period have also been flagged. One of them deals with agriculture and well irrigation. Candidates say the answer key contradicts information available on the Ministry of Culture website and material from the National Council of Museums regarding terms such as “ashma chakra” and “ahava.” They argue that when the Commission sets highly specific factual questions, the official key must meet the same standard of precision. For aspirants who did not clear the Prelims, the stakes are high. A successful challenge could affect their eligibility and, in some cases, protect a precious attempt, especially for those appearing in their final chance. Teachers and coaching institutes across the country are watching the proceedings closely, as clarity on the answer key influences how future batches prepare for similar questions. The tribunal’s next hearing on 8 October will be an important moment for everyone connected with the Civil Services examination. Until then, the debate over accuracy, language consistency, and the fairness of the screening process continues among those who sit for India’s most competitive public examination every year.
