The open lesson

It is free and does not commit you to anything. You keep the note and the handout whether or not we continue. I record only the board and my voice, never the students. The link is personal to the student who reserved the seat.

Lessons

Online, in a group of up to four students or one-to-one, at a fixed weekly slot. Programmes and fees are published on the programmes page as a monthly amount per student. The fee you start with does not change for as long as your child continues.

Payment

Monthly, at the start of each month, by international bank transfer, Revolut or Wise, in euro. An invoice is issued for every payment. If another arrangement suits you better, tell me and we will sort it out.

Absences and cancellations

If your child cannot attend, let me know as early as you can. The group lesson goes ahead and your child receives the notes and the board recording. If I have to cancel a lesson, it is made up.

Stopping

You can stop at any time with a message before the start of the next month. If I think I am not the right person for your child, I will say so and tell you what to look for instead.
