Can I take a lesson now or do I need to book in advance?

A Lesson Request needs to be sent and accepted to successfully book a lesson.

A student sends a lesson request

A lesson request sent by a student can book lessons 12 hours later at the earliest.

A teacher sends a lesson request 

If you and your teacher have agreed to an instant lesson, your teacher can use the Lesson Invitation feature to send students a lesson request to start a lesson within 15-30 minutes. After you accept the lesson request, you can start the lesson soon! 

Note that your lesson is only booked when a lesson request is accepted.
