UK Students told: turn up or face expulsion

The Guardian has reported that a number of British universities have forced their students to sign legal contracts as a condition of taking courses. These contracts specify that the students will observe "good behaviour" and will regularly attend lectures and tutorials.

But the National Union of Students has condemned these contracts, calling them "one-sided," as they do not place any obligations on universities (for example, in terms of quality of teaching).

When I was enrolled in the Technical University of British Columbia (R.I.P.), we were required to sign a contract as a condition of enrollment. However, if I recall correctly, this contract merely required us not to engage in crime, academic dishonesty, etc., without imposing any specific requirements to attend lectures. British Columbia courts have ruled that there exists a contractual agreement between the student and the post-secondary institution, defined by the official literature (calendars, etc.) produced by the institution, but (TechBC aside) there haven't been any actual contracts in place in BC universities.

Does your post-secondary institution force students to sign contracts as a condition of enrollment? If so - what do these contracts contain?
