Hey Saket,

You should contact the higher authority of that examination whose password you have forgotten. Just contact through Email and Contact number provided on the official website and tell them the proper reason, for getting a new password. I will suggest you to write your username and password from next time, for any examination that you apply for, in your diary or computer. This will help you to recall the password if you forget it.

I hope you have got your answer.

Good luck !
