If you've lost your CET (Common Entrance Test) application, the first step is to check your email inbox and spam folder, as the application number or registration number might have been sent there. If that doesn't work, you can usually retrieve your application number by visiting the official CET website and using the "Forgot Password" or "Forgot Application Number" option, which often requires your registered email or mobile number. You may also need to provide other details like your date of birth or security question answer.

Here's a more detailed breakdown:

1. Check your email:

Look for the application number or confirmation email in your inbox and spam folder.

2. Visit the official website:

Go to the official website of the CET exam you are applying for.

3. Use the "Forgot Password" or "Application Number" option:

Look for a link or button that says "Forgot Password," "Forgot Application Number," or something similar.

4. Provide required information:

You will likely be asked to enter your registered email address or mobile number, and potentially your date of birth or security question answer.

5. Follow the instructions:

The website will guide you through the process of retrieving your application number or password.

6. If you cannot retrieve it:

If you are still unable to retrieve your application number or password, you should contact the CET authority's helpline or visit their office.
