Dear Sravani, if this is regarding CAT exam, please write to CAT helpdesk at cat2019@iimcal.ac.in  along with the copy of your Admit card. Let them know it is not clear and if you would be allowed to the exam hall without any issues or would they issue a new admit card. However if it is regarding any other entrance exam, please do help with the exam and we shall help you with their helpdesk email id and you can reach out to them.
