For those who accelerated in subjects in VCE, how important do you think it is to spend time on your 1/2s when you are going to be completing your 3/4s at the end of year. It seems sort of counter productive to put too much effort into your 1/2s when you take into consideration that your performance in them has no direct impact on your final VCE scores. Next year I will be doing 3/4 Psyc and Physics and 1/2 Methods, Further, Lang and Chem. Is there anything you wish you did differently during VCE in relation to balancing work between your 3/4s and 1/2s??
Thanks in advance!!!! 
Broadly, I think the advice here has been pretty sound!

It's definitely a balancing act. Like, your 3/4s should be your priority - that much is pretty clear - but to what degree? Whilst your 1/2 subjects won't
directly impact you or your ATAR, as you've alluded to, they're still important. Reinforcing Aaron's comments, it's important to be mindful of how you're going in your Year 11 subjects, too.
This whole thing is very subjective, because the amount of time you spend on whichever subject will likely be the result of multiple factors (competence, experience, enjoyment, necessity etc.), but if I had to rank "importance", I'd probably go with something like:
1. Psych & Physics
3. Methods & Chem
5. EngLang
6. Further
But take this with a huge grain of salt - I'd just back your instinct with whatever you think is right for your particular situation.
