Um, yeah. Presumably you have similar privacy rules there as here, though? If a new student comes to me as their tutor and wants to change subject, then if the bureaucracy (places, qualifications) works, they can, and noone will tell their parents if they don't; indeed, I'm specifically not allowed to give a student's parent information about them (any more than I would give it to random member of the public).
