actually i will have to agree with you on that. But is a double major harder?
From the perspective of an Arts student.
A major is just 8 subjects in a particular sequence. You do the same number of subjects (24 overall) if you do one major or two. It's just that if you do two majors you're doing 8 subjects in two particular areas of study (two level 1 subjects, three level 2 subjects and three level 3 subjects).
So the difficulty doesn't really change. In fact it could be argued it's easier because you're accumulating knowledge in that one field and just doing more subjects relating to that field, as opposed to doing electives from other fields.
Majors don't go on your transcript, to clarify. The only reason we do majors at all is a) because we have to do at least one according to UoM undergrad degree rules b) because they're a pre-req for certain courses. Otherwise it's just synonymous with doing 8 subjects in a certain area of study.
