The provisional answer keys for the CSIR UGC NET December 2025 exam have been released by the National Testing Agency (NTA) and the Council of Scientific and Industrial Research (CSIR). Candidates can access the answer keys and their recorded responses on the official CSIR NET website. An objection window is open until January 1, 2026, allowing candidates to challenge answers by paying a non-refundable processing fee per question. Challenges require academic proof, and a panel of experts will review them to prepare the final answer key and subsequent results.
