Hi,

Following are some of the options which you can try to get the admit card again-

• If you recieved e-mail of admit card you can download it from there
• If You downloaded the AIT card on your own PC/laptop that it mUST have been saved in download section or office notes try to find it there.
• Try to reach the cafe where you have download and printed your admit card. Of you are lucky you can get that from their computer.

If above does not helps, try to send an e-mail to nta neet regarding your problem. If they consider it you may get your problem solved.

Hope it helps.
