hey hema

this  year aiims admit card this bit different than previous year aiims card. but don't worry and don't need to fill these columns beforehand. i will suggest you to wait and fill columns infront of invigilator as per their command. this year in neet also invigilators asked candidates to stick their photograph in admit card at the time of signature. so i think you should wait and fill it in your exam hall. 

goodluck
