The tutor will spend over the given hour to teach you at least 15 minutes and over... also i was heard before that rules are given from the music co that the tutor need to arrange the time to lengthen the period each lesson, so the student can spend extra long time to learn certain things...and the most important that you can have enough time to ask the tutor if you have question.... You know i let my kid to learn in PARSONS since group class and private lesson around 10 lessons also with $125/45mins with no grading (elementary) but now is $160/45mins but usually 1.25 hr preparing grade 3 exam next yr..... You can imagine .....
