Your teacher decides whether or not you may leave the class, signs the slip and gives you a teacher card. At the end of the appointment the slip will be marked with the finishing time. See us at any time when we are free but especially whan an appointment diary is at hand. If not, an appointmant will be made to see one of use at a later time. Some areas are listed here.
Nothing is too small or big to be discussed.
If you want to talk, it can be done.
