Hello,

Yes, you can usually change a wrongly attached certificate during the correction window, but it depends on the specific application or exam authority. Here are key points:

1. Check Official Guidelines – Visit the official website to confirm if document replacement is allowed.
2. Correction Window Availability – Ensure the correction window is open and allows document changes.
3. Required Documents – Keep the correct certificate ready in the prescribed format.
4. Official Support – Contact the helpdesk if the portal does not provide a direct option.
5. Final Submission – Verify changes before final submission to avoid further issues.

Hope you find it useful !
