CAT 2026 Correction Window: Key Facts

What Can Candidates Edit?

IIM Indore allows candidates to edit only their uploaded photograph, signature, and test city preferences, and no other field of the form. The source says other details, such as personal information, date of birth, academic percentages, and work experience, are locked. Candidates who need to fix those should contact the CAT helpdesk [VERIFY the process].

Who Can Use the Correction Window?

The window is only for candidates who have already submitted the form and paid the fee. Candidates who did not finish registration and payment cannot submit a fresh application through the correction window. The source says the registration window closed on 22 September, while other reports say 24 September [VERIFY]. 

Seven Things to Check Before the Window Opens

The source gives these pointers. Items 3, 4 and 7 contain specifics that need official confirmation. [VERIFY]

1. Login details. Keep your CAT ID, password, and registered email and phone accessible.
2. Submitted application. Review your submitted form and keep your documents handy to cross-check.
3. Photograph. Make sure it is recent, clear, and meets the official size and format rules.
4. Signature. Make sure it is legible, matches your actual signature, and meets the upload rules.
5. Test cities. Review your city preferences, since these can be edited.
6. Locked details. Check personal and academic details. If something is wrong, you cannot edit it in this window.
