Record on class in date and time

The teacher can create to himself the schedule with date and time of the beginning of each occupation. The pupil can записатья on the chosen occupation. I correctly understand?

And we will allow it is possible to deliver restriction for an event that only one pupil could register? After record the event became inactive and further record is already impossible on it

there's something untranslated I don't understand,sorry.

In the event you can decide, how many users can participate (If 1, then write one). You then need no waitinglist?!
Then further record is impossible.
Or you set a waitinglist too, then if a user is taking back his signup, then the next (or the chosen one of the teacher) is attendee.

Thanks. You have very much helped to understand

I hope so. You're welcome
