This shall not be any problem. All they look for is your clothes and foot wear. So make sure that you wear simple clothes without any fancy embroidery and long pockets. No chains hanging from pants or shirts. No full hand clothes. They should be short sleeved with no collar. For girls a simple kurta and palazzos and for biys it is a shirt and a formal pant. Also no boots, shoes. It should be sandals. Socks are not allowed. But due to Corona, gloves might be considered but we have to hear rom NTA regarding this. No jewellery of whatsoever metal is allowed. And even if you have shaved off your head, make sure you take a recent photograph as well along with the admit card. That should be fine.
