Courses consist of 15 classes per semester.

If possible, up to two missed classes can be made up for in other groups by prior arrangement within the same semester. (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. (Unless pandemic-related restrictions make it impossible.)
