Dear Sathish,

If you have lost your hall ticket of SSC (10th) and intermediate (10+2) level qualifying exam, then you should contact with the respective state/central education board under which you have qualified these exams and request them to issue duplicate hall ticket/ admit card .

You can e-mail to their official mail id or contact to their helpline no for requesting!

Don't worry ,Do as I have said above and wait for  further proceedings, you will surely get your admit  card.

Hope this helps !

Best wishes !!
