Am I under any obligation after the taster lesson?
No, after KLU's free trial lesson, you are not committed to anything. Nothing will be charged automatically and you will not receive an invoice.
After the taster lesson, KLU will send you an email offering you the chance to enrol on the full course. It’s entirely up to you. If you do nothing, that’s the end of it. You can sign up for a taster lesson via the course page for the relevant course or via klu.nl/free-trial-lesson.
