Hi there,

Your question is not complete as its not giving any information about the exam with which that admit card is related to.

But still, I can help you in a very general way:

1.Search the soft copy of the admit card in your PC/Lappy/mobile because you must have downloaded it once for sure.

2.If the above mentioned step is not useful: Then try to search for the link through which you can download the admit card foe one more time. (The examination authority keeps the link open till the date before the exam)

3.If the above mentioned step is not useful: Then write a mail to the examination cell or call them on their helpline numbers and tell them about the mishap.

If you will try you best then you will definitely be able to find your admit card.

All the best for the exam (which ever it is ;)

I hope this will help you!!
