Hmm, interesting. Some universities in Britain are forcing students to sign good behaviour contracts where they promise to attend lectures and tutorials, and agree that  any breach of contract may lead to expulsion:

Thousands of undergraduate students are being forced to sign good
behaviour contracts with their universities and warned they could be
expelled if they breach regulations, the Guardian has learned.The
contracts put the onus on students to attend lectures and tutorials,
but have been condemned by the National Union of Students. The NUS claims the contracts are “one-sided”, and do not spell out what
standard of teaching students should expect to get for the
£3,000-a-year top-up tuition fees they are being charged.

What do you think of that?
