I'm in love with essay writing, which is so geeky. Part of the rationale for picking my subjects next semester was that the assessment would be essay based with no exams *happy sigh*. That's probably why I like arts, just essay writing. But also, you don't have to accept assumptions while essay writing like I think you have to in law (as in, you have to assume that upholding the law is a goal you want to work towards and that what's "right" is based on what already exists in writing).
Have you done any analytical/reading type arts subjects? I'd be curious to know how much time you needed to spend on them [as in non-contact hrs pw]
Non-contact hours in arts subjects like English can range from about 5 a week (like, the first few weeks) to countless (essay build-up time). When I did UMEP English I had to read one text a week, which was insane when I was reading stuff like A Portrait of a Lady. My now less ready subjects still involve quite a lot of readings a week. Probably not as much as law students get, but the difference is that I actually do my readings.
