GATE 2026 Answer Key Challenge Window Open Soon: Don’t Miss the Deadline to Submit Objections

The GATE 2026 Answer Key Challenge Window is opening soon, and candidates must act quickly if they wish to raise objections. The GATE Provisional Answer Key 2026 has been officially released on February 22, 2026, and the objection process will remain active only for a limited time before the final key is prepared.

The answer key and GATE 2026 Response Sheet have been uploaded by the Indian Institute of Technology Guwahati on the official website gate2026.iitg.ac.in. Since the result is scheduled for March 19, 2026, candidates must carefully review their answers now.

All you get to know here is what you should do immediately, why the challenge window matters, and how to avoid common mistakes while submitting objections.

Why You Should Check the GATE 2026 Answer Key Now

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.
