Learn how to view the course invitation code.

The invitation code of ordinary courses is sent by the inviter to the invitee, and the viewing method is as follows:

1. If the invitation code is received by email or SMS, you can check it in the email or SMS.

2. If the invitation code is received by QR code, you can scan the QR code with your mobile phone and then view the invitation code information.

3. If the invitation code is issued by the school or unit, you can consult the relevant person in charge to obtain the invitation code information.

It should be noted that the invitation code of a general course can only be used once. If you have already registered with this invitation code, you cannot use this invitation code again.
