The academic years at Oxford are faster-paced than those at Columbia and almost all other institutions. More work and more essays and more readings in less time and in fewer years than other classes. Cumulatively, I will have worked just as hard at Oxford as I did at Columbia, except I will have accomplished more work in a shorter time with fewer classes: 28 weeks per year at Columbia vs. only 24 at Oxford, and 12 hours of class per week at Columbia vs. only 1 hour of class per week at Oxford.
The academic year at Oxford feels as short as the paragraph you have just read. And, eight weeks, feels shorter still if one is working hard.
