So people on different courses do different amounts of work? Well, how amazing!
For the record, on my CompSci degree, we had four hours of lectures six days a week, 9 am to 1 pm. We also had two 2-hour practicals in the afternoons. That's 28 hours of scheduled work per week. In addition to that, we had projects that we had to work in, and programming course work. I see the medical student started at 10 am. No such luck for us. In large measure, we simply ended up skipping the 9 am lecture.... Natural Science Part I entailed a similar workload - I think we had three practicals, rather than 2, but on two days a week, we only had 3 hours of lectures. I still remember the regular dash down Tennis Court Road from the Old Museums Site to the Chemistry Department at 11 am - 300 cyclists in tight formation.
In the meantime, there were rumours that the Land Economy course at the same university involved just 2 hours of lectures a week. That made the student newspaper at the time.
My nephew has timetabled (I believe) 7 hours lectures per week on his English degree.
