What does every course include?
A course is a set of pages a learner reads at their own pace, with questions that are marked on the page and exercises that run in the browser with nothing to install. The Maestro answers from whichever page the learner is on, in the language they read the course in.
A free course can be read whole without an account. Signing in adds a Maestro and the exercises.
Is there a way to pay less?
Two or more people who buy a course together each pay less: 15% off for two, 30% for three, 35% for four and 40% for five or more. How buying with friends works.
A learner who has already bought a course pays 15% less for a second one, 30% less for a third, 35% for a fourth and 40% for each one after that. How buying a course works.
Can a course be refunded?
Yes. Any paid course is refunded in full within 7 days of the purchase, for any reason, by writing to hola@heymaestro.app. That includes a course bought in pre-sale.
