My teachers

A teacher and a student are linked by invitation. The teacher sends you a link; open it while signed in to your account and press "Join". From then on you are their student. The link works once and for a week: it is meant for you alone.

You can have several teachers. What it gives:

A teacher sees your name and e-mail address, and of your results only what was sent to them.

Leaving a teacher

In "Settings", under "My teachers", press "Leave". Access to that teacher's private material ends with the link. Results already sent stay with them.

If a link does not work, somebody has already used it, the teacher has revoked it or it has expired: ask for a new one.

Only students have teachers: a teacher's account cannot accept an invitation. The role is chosen at registration and does not change afterwards.
