Hello sir I request you to please help me with the examination / institution you're concerned about so that I can check and provide you the exact information, how you can receive the credentials for appearing in examination.
As the process vary from portal to portal. You can also contact the administration of the college regarding the same.
Feel free to comment if you have any doubt
Good luck
