If your counselor has sent you an email invitation, you can click the counselor invite code from the email to add it to your account.
Alternatively, if you have an invite code you can manually apply it when logged into your account. Click My Account, then Settings. Scroll down on the settings page, click Add Invite Code, and enter the counselor invite code. Follow the prompts to apply it to your account.
You will be prompted to add your full name too.
Make sure to enter your name exactly as it appears on the ID you’ll use for the test. The DET supports 18 different alphabets, so you can enter your name using any of them. Your name will appear the same way to your counselor. To see which alphabets are supported, go to My Account and click on Site Language.
