Hello,

If you've made a mistake in your GATE application form, such as entering incorrect qualification information, you may be able to correct it during the correction window that GATE provides. The correction window is usually opened after the application process closes, allowing candidates to rectify specific errors like qualification details, category, or exam city.

Also, you should check the official GATE website for the correction schedule and the list of fields that can be edited. If the mistake cannot be corrected, contact the GATE organizing body immediately for further guidance.

Hope it helps !
