Quick Summary
Registration Deadline: Sep 22, 2026 | Fees: ₹1,350–₹2,700
The CAT application form correction window is a brief, time-bound portal typically opened by the conducting IIM shortly after the registration deadline. It allows candidates to rectify specific errors in their submitted forms. For 2026, the registration deadline is September 22, 2026, with the correction window expected to open shortly thereafter.
The CAT application form correction window is not a full-access portal; rather, it is a restricted facility provided by the conducting IIM (IIM Indore for 2026) to ensure data integrity. It is critical to understand that this window does not permit changes to every field in your application. Typically, candidates are allowed to update minor details such as photograph uploads, signature files, or specific academic score entry errors. However, core data points like your registered email ID, mobile number, or the primary category selected during registration often remain locked to prevent fraudulent activity.
Aspirants should prepare to act immediately once the window opens, as the duration is usually limited to 2-3 days. Missing this window means your application will be processed with the existing data, which could lead to complications during the document verification stage of the MBA admission process.
Key Points for Students
- ✓Only specific fields are editable (e.g., photo, signature, test city preferences).
- ✓The window is open for a very short duration, usually 48 to 72 hours.
- ✓No major changes to registration credentials are permitted.
- ✓Always cross-check the official website for the exact list of editable fields before attempting changes.
According to official notifications for the 2026 cycle, the CAT application fee is approximately ₹2,700 for General, EWS, and NC-OBC candidates, while SC, ST, and PwD candidates pay approximately ₹1,350. These figures are based on current institutional disclosures and are subject to change by the governing body. It is essential to note that while the correction window is a free facility, any attempt to create multiple registrations to bypass errors is strictly prohibited and can lead to the cancellation of your candidature.
Candidates should rely solely on the official CAT website (iimcat.ac.in) for updates. Avoid third-party portals that promise 'guaranteed' changes to restricted fields. Always verify your form status against the official prospectus to ensure compliance with the latest UGC and AICTE guidelines regarding entrance exam integrity.
