Dear Student,

You have to fill the proper name in proper place like in place of father you have to enter the name of your father an din place of mother you have to enter the name of your mother. As you have done mistake by entering the name of your mother in place of father so do the same thing in NEET application form also, because if you try to change then everything will contradict and you will disqualify for the exam so better if you do the thing as you have done earlier. Don't bother it will not affect anything.

Best of Luck!!!
