Dear,

As you haven't updated your father's name in your application form during correction tenure it is impossible to make it correct now.

But not to take pressure as it will not stop you from appearing NEET exam. The documents you need to carry with you on exam centre were,

=> Application form,

=> Admit card,

=> An identity card of you issued by government agencies,

=> 2-3 passport size photos.

But do remember to correct your father's name on counselling by providing relative documents. As it is important to make every possible correction on the time of counselling otherwise you might don't get any further chance.

Hope the above information helps you..

Best of luck..
