Hello Aspirant,

You have not mentioned the online portal on which you're trying to give the tests. Only registered aspirants are allowed to take test. Nevertheless, whichever site you are using must be because of a slight mistake in the username or password you have entered. Do not worry about this because there must be a link showing 'forgot password or username. Just click on that link and after that, it must be asking you to enter your email address or registered mobile number. Enter the details as asked then you will receive the link to reset your username or password or username password in your email id. Just make sure you have your email address which you provided while registering.

Regards.
