The CAT 2026 application correction window for submitted forms opens at 10 am on October 5, 2026, via the official website iimcat.ac.in. IIM Indore allows candidates who completed their registration and paid the application fee to edit only specified details in their submitted applications. The correction window remains available until 5 pm on October 6, 2026, and sources note that no further extension is provided.

Across outlets, the editable fields are consistently listed as the candidate’s photograph, signature, and test city preferences. Candidates are instructed to log in through the “Registered Candidate Login” section, access their submitted application, make the permitted changes, and then submit the corrected form. After correction, candidates are advised to review the updated information carefully before final submission.

The outlets also reiterate the broader timeline for CAT 2026: the exam is scheduled for November 29, 2026, and is conducted in shifts. The corrections are intended to let candidates rectify limited application details ahead of the exam and subsequent admissions processes.
