Dear Aspirant,

The correction window was open during the month of April 2020 and since then it has been closed for any changes as the late is now over.  If you have tried recently and if no changes are allowed, then it is simply not possible

If there are no gross mistakes then you will get the admit card to appear for the examination.  Please appear for the examination, get good grades then when you are called for the interview explain what had happened and the error is regretted.

Good Luck
