The GATE 2026 Answer Key Challenge Window is now officially live on the GOAPS portal, following the release of the provisional answer keys by IIT Guwahati. Candidates who appeared for the exam on February 7, 8, 14, and 15 have until February 28, 2026, to submit their objections. Each challenge requires a non-refundable processing fee of ₹500 per question (for Indian candidates) and must be accompanied by valid documentary proof from standard textbooks. Since the final results—scheduled for March 19, 2026—will be based entirely on the revised key, this three-day window is a critical opportunity for aspirants to ensure their scores accurately reflect their performance.
The GATE 2026 Answer Key Challenge Window is officially open from February 25 to February 28, 2026. During this period, candidates can log in to the GOAPS portal to contest the provisional answers by paying a non-refundable fee of ₹500 per question. Each objection must be accompanied by a clear PDF containing supporting evidence from standard textbooks, as handwritten notes or coaching materials will not be considered valid. Once the window closes, no further requests will be entertained, and the expert committee will finalize the keys for the result declaration.

Many candidates ignore the provisional key, assuming the evaluation will be correct. However, reviewing the answer key is important because:
Even minor errors can affect your final score.
GATE scores determine admission to M.Tech, M.E., and PhD programs.
Public Sector Undertakings (PSUs) also consider GATE scores for recruitment.
If you believe any answer is incorrect, this is your only chance to request correction before the final key is released.
