Courses consist of 15 classes per semester.

Within one semester, up to three missed classes can be made up for in other groups by prior arrangement. (Unless pandemic-related restrictions make it impossible.)

Courses are based on a minimum of 4 participants.

For siblings wanting to join a group together, I recommend choosing an age group - and thus a "programme" -  suiting the eldest.

However, if there's a major age difference, I recommend joining separate groups. In that case, of course, the respective other sibling is always welcome as a "guest" in their sister's / brother's group.
