I'm essentially interested in the content in both and am just looking for the 'easier' one in terms of work, which one requires 'less' effort and would be easier to score high in?
It may not be in your best interests to pick a subject purely for how ‘easy’ or ‘little effort’ people deem it to be. Firstly, you may not find they’re right (i.e. ‘easy’ is subjective). Secondly, you’re going to have to do the subject for a minimum of 8 months, so if you don’t enjoy it, it’ll become ‘more difficult’ anyway because you’ll be less inclined to study it. Both of these reasons defeat your intended purpose.
Alternatively, why don’t you pick subjects according to
how much you like them and
whether you need them for courses after Year 12 (you can check with
VTAC Course Search)? It’ll make your time and effort worth a lot more and you’ll feel a lot better about the subject you pick.
In terms of picking which out of Psych and HHD, I’d suggest taking a look at the study designs and building from there. If you find one more interesting or one follows your intended career path after VCE more, it’s probably the one to pick. If those contradict one another, let us know and we’ll help you out.
