Submit your attendance tokens here to track your tutorial attendance.
You can submit the tokens as you go, or you can wait until the end of the term to submit them all. Either works.
The system will keep a record of your already submitted tokens. That means you only need to submit each token once.
Note that tokens are single-use, and valid only for your tutorial section and the week in which you received it.
The number of submissions per student has an all-time limit. That means that brute-force trying random tokens will lock you out of the system permanently.
