The Railway Recruitment Boards (RRBs) release the CBT-1 answer key, question papers, and candidate response sheets for the NTPC Undergraduate (UG) Recruitment 2025. Candidates who appeared for the Computer Based Test (CBT-1) can access the documents on the official RRB websites and the common portal. Reports state that the CBT-1 exams for the relevant phase are conducted in May 2026, with another phase scheduled in June 2026, and the answer key release occurs on June 27, 2026.

Alongside the publication of the provisional answer key, the RRBs open a window for candidates to raise objections. According to the outlets, objections can be submitted until July 5, 2026 (with the stated deadline at late evening), and each objection requires a fee of Rs 50 per question, plus applicable bank charges. The RRBs state that the objection fee is reimbursed if the objection is found legitimate, after deducting relevant bank fees. A separate submission deadline and process details are provided with the official notice, and any decisions on objections are described as binding.
