Tutor+ is a free service that matches students to tutors. We do not charge any agency fees toward the client, only to the tutor.
Tutor+ Agency only charges a 50% commission fee of the first 4 lessons levied towards the tutor, not you. As a client, you are required to pay 50% of the first 4 lessons to Tutor+ immediately upon lesson confirmation, and the remaining 50% directly to the tutor after completion of 4 lessons.
This is merely to facilitate the collection of the commission fee, and there is no extra charges towards the client in any way.
