Dear Student,

The problem I have figured out by your question is that your can't open your account so that you can download your admit card.

So you might be entering the wrong ID or password, check your ID and if it is correct then there might be a problem with your password.

So the thing you need to do is, you have to reset your password, find the option "forget your password? " in your login page and after clicking in that you will be able to edit your password by entering your e-mail or phone no. or user ID.

Good Luck :)
