> completely new exams and assignments, while making sure previous years' materials are not released This seems absurd. Both MathSoc and EngSoc maintain exam banks, which students can (and do!) contribute to.

(Sometimes they're not -- the accreditation boards and curriculum committees shuffle stuff around every few years to keep up with du jour trends in education.)
