For students who have already taken one of the classes with Pip or I, we offer that they can refresh the same class for $50 per day. If you require new manuals, etc., these are charged separately.
No matter how many times you take a class (even for me as an instructor), we always learn something new; it can be the class-dynamics, the students' experience, etc.
We really encourage you to take up this opportunity to refresh on classes, so just register for a seminar/class as normal and put "refreshing" in the notes.
Please note, that there must be at least one student paying the normal rate, it is not viable to run the class purely for refreshers.
