Hello Aspirant,

Do not worry .Since you know what exactly happened to you email address, find a way to recover that email address. You can use google assistance to know the exact set of instructions for the recovery . As most exam registration will ask for both email and a phone number ,you can find the user id by checking the messages sent to your registered phone number by the authority . Mostly during when a candidate register at first , a text message with user id and other details will be sent to the registered phone number so check your inbox.  After finding the user id , go to the login page and use the "Forgot password" option to update your password. And once you login using the new password, kindly save the details to avoid the same problem in future. You can use the " Save password" feature and save your details , this way you can always go google browser settings and find your respective user id and password, this will helpful for all such processes .

All the best
