Hello Sachin

If you cannot find your CET User Id and Password, check your registered email id. Most of the examinations send the user id for email confirmation. If it is not there, kindly write a mail to the council regarding your query, i.e. that you have lost your user id and password through your registered email id and also mention other details like your rank, date of exam, date of birth, academic details so they can confirm it that the email is genuine. You can find the email address in the official website.

Hope it helps you.
