I asked my friend who is doing Commerce/Law what she thought. Here is her response:
Hi vce01 -
1. either should be fine for employment, there should be no huge effect but you should consider what path you want to take after your degree
...this was probably one of the considerations of unimelb turning law into JD-only (postgrad) which is overrall not that bad an idea to be honest.
it really does depend on your majors/disciplines in each of your degrees and in the end if you do choose to do a double degree that is 5 years (my point: do something you won't hate)
many, many people who graduate from a law degree don't actually go into law. i've found that a lot of comm/law graduates have 'strayed' into the commerce side; i know quite a few people who've gone into investment banking and general finance/accounting areas, but lots go into management consulting.
i'm doing comm/law (at coblin's uni) so i can't say i'd know a lot about arts/law kids' employment prospects but from what i understand (and have heard) to be the general consensus is that the arts component is generally what keeps them sane throughout the degree (this is also true for commerce/law kids). majors in foreign languages and philosophy/history are quite popular - so if you enjoy these subjects now; you'll definitely enjoy arts/law.
there isn't really a definitive answer to this question
it's more or less just knowing what you'll like etc.
2. it is totally possible to avoid math in commerce. the commerce degree has a lot of different disciplines that you can take - among these are accounting, finance, economics, management/marketing, and i think unimelb has introduced a new 'business major' which is a major requiring you to complete subjects from 3 of the different sectors (eg accounting, management, economics).
economics can get a bit mathsy (direct all enquiries re economics to coblin haha!) but the other subjects are all at most simple math and really quite logical.
if you want to avoid math at all costs - go for management
it's all theory!
3. again with this one it really depends on the subjects you do. both arts/law and comm/law degrees have very little contact hours.
i've had about 13 or 14 contact hours per week (2.5-3 days p/w inc breaks) for the last 4 semesters (including this one). there's a general requirement for a lot of autonomous work/reading/writing (which of course i have blatantly neglected to do) which is why the contact hours are so low compared to courses like science (which have pracs/labs) and med (which have clinicals).
i think each language subject is about 4 contact hours each - so if you balance your arts and law degree you'd have between 14 and 16 contact hours (maximum 16).
there really is no difference between arts/law and comm/law with respect to contact hours - you're going to end up with a pretty spare timetable either way.
anyway hope all of this helps! i've posted this under coblin's account because i'm too lazy to create my own
but yes happy reading!
cheers,
anny.
