Hello,

The board sends the confirmation mail to the given mailaddress or message to the registered number. If you haven't received it then look for helpdesk of the board and ask them to send you a confirmation mail that you have registered for the entrance.

They are the only person who can help you to get the details or process to solve the problem. They will let you know what was the problem for which it was not sent or if there is no problem then they will send you one.

Hope it helps!
