Combination of CompSci and Art, literal mishmash, as when I was doing it we were part of both Faculty of Science and Faculty of Art. My average day consisted of 8am till 6pm "compulsory"* with a realistic need to extend to 9-10pm just to cope with the workload, a combination of labs, seminars and lectures. My full terms were between 11-13 weeks.
Cambridge full terms? 8/9 weeks.
So basically unless Cambridge has circumvented the time-space continuum, them having a higher work load is complete and utter rubbish. They might have comparable, but certainly not more.
