Hello Praneeth,

I am also appearing for the cat examination this year. As far as your query is concerned I would suggest you to right your  father's name(which is starting with S) in the middle if it is also mentioned in your aadhar card and pan card .

And if by any chance it is mentioned only the initials S in your pan/aadhar card then I would suggest you should fill only S in the cat application form.

Note :-

Keep in mind that your name in the application form should match with what is mentioned in your aadhar card /pan card .
