Hello,

Try to contact to the board and ask them for rectification if possible. For this only it is always said to be enough alert while filling the forms. Disadvantage is your application may be rejected if your eligibilty is wrong or they won't forward your application for futher process.

So try to put a mail to the board about the issue and ask about the solutions can be done.

Else you have to change it during your document verification time. They will ask you about the mistake you have done and they will rectify it.

Hope it helps!
