The CAT 2026 form correction window opens on October 5, 10:00 IST. It closes on October 6, 17:00 IST, per the September 29 notice. Candidates can fix photo or signature and change test city. Missing this window risks form rejection or inconvenient test travel.
Only applicants with successful fee payment can access the edit window. Log in using registered credentials to review your submitted application. Name, date of birth, email, mobile, and category stay locked for integrity. Confirm payment status and download the current form before editing anything.

Use the dashboard link for Application Form Correction during the stated window. Replace photo and signature, if needed, and choose a preferred test city. Select Validate to check errors, then Submit to lock edits. Download the updated form and save the acknowledgement for records.
Only three fields are open: photo, signature, and test city preferences. Identity and contact fields remain fixed to avoid downstream verification conflicts. If details differ from your identity proof, carry supporting documents on test day. Use the table below to review what you can change now.
| Field | Status in correction window | Practical tip |
|---|---|---|
| Photograph | Editable | Use recent colour photo on neutral background; face uncovered; avoid filters or shadows. |
| Signature | Editable | Sign in dark ink on white paper; scan cleanly; crop tightly before upload. |
| Test city preferences | Editable | Reorder early; prioritise nearby centres with dependable transport and backups. |
| Name, date of birth, email, mobile, category | Locked | Cannot change now; keep matching ID proofs ready for verification. |
Upload a recent passport-style colour photo with a clear face and neutral background. Avoid caps, tinted glasses, filters, harsh shadows, or busy surroundings. Sign in dark ink on white paper, scan cleanly, and crop tightly. Save as JPEG, correct the orientation, and keep file size moderate.
Log in early on October 5, as popular cities tighten quickly. Rank nearby cities with reliable transport and backup options. Consider travel time, morning curfews, and festival traffic while prioritising. Reorder preferences decisively; hesitating until evening invites avoidable slot pressure.
After the window closes on October 6, edits lock, and the portal refreshes. Watch the official portal for admit card timing, typically announced in late October. Note the CAT test date, November 29, and plan mocks, documents, and travel now.
