All teachers provide specialized private instruction to all interested students. To ensure the pace of group classes, there may sometimes be a prerequisite to joining group instruction. Each class is generally an hour in length, and can sometimes be extended by the discretion of the teacher.
Small groups are formed as per the discretion of the teacher. If a teacher has a number of students at a similar level, he/she may approve the students to learn together. Students coming in wishing to learn as a group have to go through auditions with the teacher to make sure they are compatible to learn together. This is to ensure maximum quality of instruction.
