When you have downloaded your Admit card from the official website, a copy of your admit card is ideally sent to the registered email id. Please check if you have it in the inbox of the Registered Email Id. Or else you may have to wait for NTA to reopen its official website for downloading the admit cards. This is not a guarantee. But you can reach out to NTA at their helpdesk to see what can be done. Please mail them from your Registered email id at: neet @ nta .ac.in
