I mean that there is usually very limited tolerance for repeat cheating, in the small amount of experience I have. You might not get expelled at first offense (unless you are leading a cheating ring of some sort, something that happened at my high school) or it involves publishing research, but a second or third generally does result in expulsion.

This is assuming that the school actually reached an incriminating verdict, ignoring possible incompetence and/or apathy towards catching and "convicting" cheaters.
