UPSC Prelims 2026: The Union Public Service Commission (UPSC) will close the objection window for the Civil Services Preliminary Examination (CSE) 2026 provisional answer key today, May 31, 2026, at 6:00 PM. Candidates who wish to challenge any answer in the provisional key must submit their representations online before the deadline through the official portal.

In a major reform aimed at enhancing transparency, UPSC released the provisional answer key on May 27, just three days after the examination on May 24. This marks a significant departure from the earlier practice of publishing answer keys only after the completion of the entire recruitment process.
