hello,

Once application form is submitted then it can't be changed. If the board gives any dates for correction and category correction is allowed then only you can change it. But it is not provided. You can't change it now.

due to this only it is advised to gather all the information and write it down and then do rrecheck then fill the form. Guidance PDF is also provided but No one reads to throughly.

Anyway you can't change it now.

Hope it helps!
