The reason that degrees like English literature have less contact hours is that it has been deemed more productive for the students to go and read the necessary material themselves than to have it read to them. Degrees like pharmacology necessarily have more contact hours because the degree is lab-based. Contact hours are a poor way to quantify the difficulty of a degree.(Original post by pure_joy)
Sorry, didn't mean to wind you up. They aren't easy as such, especially not at a good uni like UCL. But they are easier in the sense that workload is less structured and all of them require less contact hours than for example Chemsitry- if any Coldplay member did something like Chem, they only instrument they would have had time to use would be a lab spectrometer.
