Hello Aspirant

You shouldn't worry about this little issue regarding the spelling of your Father's name, because Aadhar card had this issue while converting from English to Hindi or vernacular hence there is some error in the spelling.

There won't be any problem for you if your Father's name in all your documents like 10th & 12th marksheet, school leaving spells exactly same in English.

To stay on a safer side you should ask your father to rectify the spelling mistake before your counseling.

Hope this helps
