If you are late for a class, then depending on the tutor's availability, he/she may give you a full class. Otherwise the class will be shortened and counted as a full one too. If you are too late, without any notice, then your class "burns out" (there are no refunds for this class).
If you have force majeure after the approval of the schedule, you can ask to reschedule the class. Classes must be rescheduled for the same week.
If you have an acceptable reason for taking a class next week, you must state it, and we will discuss it with you. If the class is rescheduled to next week, nothing can be moved from next week to another one, and the class that was not held will burn out.
If you have reasons like illness or a long planned trip, we can move more than one week, but only within one month, postponing to the next month is not allowed in this case. It is not permitted to reschedule classes quite often, in this case you can try to cancel classes for a month, but we do not recommend doing this frequently, as irregular classes may affect the quality of your progress.
