UPSC Provisional Answer Key 2026 PDF for Prelims (GS Paper 1 & CSAT)

The Union Public Service Commission (UPSC) will release the Provisional Answer Key for the Civil Services Preliminary Examination 2026 after the completion of the examination held on 24 May 2026. This step is part of UPSC’s effort to improve transparency in the examination process. The provisional answer key allows candidates to review the officially accepted answers for both papers and raise objections if they find any discrepancy. Unlike earlier years where answer keys were released much later, UPSC is now making the process more candidate-friendly by introducing an early provisional release along with an objection facility.
