With a one-on-one class you obtain maximum interaction with the teacher and benefit from having very close attention paid to areas in which you need to develop.
Tutoring sessions are structured according to the specific needs of the learner (or learners) and do not require a course textbook. Classes can be arranged for one person or a small group of two to a maximum of three persons. The cost per person for each lesson decreases with each additional person (see: rate calculator). Tutoring is appropriate for any level of learner including complete beginners and advanced students.
