I graduated from one of the top 5 British universities in the mid 90s with a 2:1 degree in History, and I have to say that it was one of the easiest thing I ever did. I had class and lecture time of 4-6 hours a week, and spent another 8 hours reading and writing essays. The essay requirement, which contributed almost half to the degree grade, was only about 12 3,000 word essays a year. I had so much free time that I turned my part time job into a full time job, working 35 hours a week.
Of course, I should have worked harder, and I would have learned more if I had, but I was 19 and 20 years old and it was just so easy to get a good degree without working at all. I know I was far from alone in this.
Every degree course is not the same, and no doubt others may have worked long hours to earn theirs, but my own experience has left me with no respect for UK degrees, to the extent that when I read CVs from candidates I consider a third level degree irrelevant.
