Removed classes and students don’t show on the dashboard, in its totals or in the spreadsheet, and they can’t practice (a removed class’s sign-in link stops working too). Their answers are kept, so you can bring them back — or, once you don’t need them any more (a class from an earlier year, say), delete them for good: their answers, progress and streaks are erased, and that can’t be undone.

For days when a class is busy with other things — exams, a project, a trip. On frozen days, a student who doesn’t practice keeps their streak, and the day counts toward their weekly goal, like a day with nothing to do. Practicing still counts as usual.

Every card with any of the tags you pick goes in. You can add or take out cards afterwards, and when you tag more cards later, the deck offers to add them too.

The deck starts switched off: switch it on when students should review it.

One card per line: the word, then a tab or a dash, then the meaning. A list exported from Quizlet with a tab between term and definition pastes straight in.
