After successful matching, the parents/students will first pay Toby Lesson the first two lesson tuition, which will be regarded as the referral fee for the tutor. The tutor will not be paid for the first two lessons. In order to ensure the effectiveness of tutoring, the standard length of each class is 1.5 to 2 hours. After the first lesson, parents/students can decide whether to continue to hire the same tutor. If parents/students continue to hire, parents/students need to pay the tutors directly starting from the third lesson.
