SOPP458: Total Organist has the taste of being very intriguing and complete

This question was sent by Alessandro, and he writes: Dear Vidas "The Total Organist" has the taste of being very intriguing and complete. But from your video I have not well understood: 1) The total duration of the course 2) The total price of the course 3) If one has to master every section of a level before passing to the next level, or the pupil can choose exercises by carefully looking at what he can already do and knows and what are still his/her weak points? 4) The pace of tuition: if I'm a slow learner what happens then? May I see and re-see the videos again and again? May I also write an mail asking for explanation (I'm sure that I may, since I did it in the past) 5) Can i get in touch with other learners Sorry for bothering you, but I need to Clarify these points Thank you very very much for your answer Alessandro
