Hey pari.j! How are you going?
In general, I'd recommend not thinking too much about scaling if at all possible when selecting subjects - perhaps using it only as a tie-breaker in the case of all other things being equal. Here's my rationale:
→ Scaling in the VCE system doesn't "reward" or "punish" you for studying certain subjects. In fact, the whole purpose of scaling is to make things more of an even playing field (
more here if interested). If you "benefit" from subjects scaling up, that's really just accounting for the fact that the cohort was deemed more competitive. Equally, if you are "disadvantaged" by subjects scaling down, that's really just accounting for the fact that the cohort was deemed less competitive.
→ In my view, selecting subjects based on scaling alone is problematic and potentially actually counter-productive. Even taking the above point into consideration, it might be the case that you enjoy or are more passionate about one subject than the other. In that case, there's an extra factor in play. If you choose a subject that typically scales up but actually don't find it at all enjoyable and have no motivation to study, you might "benefit" from scaling (again acknowledging that this is really just neutralising things), but in my view, you're less likely to do well in the subject due to lack of motivation/interest.
Of course, that's not to say you shouldn't select Specialist Maths - not at all. I'd just personally try to remove scaling as a primary consideration if in your position.
Through VCE, I was super bitter because only one of my six subjects scaled up (and only by a little bit - English Language), so I thought I was being punished for my subject selection, and that the system was totally unfair, so I get that scaling can be a big consideration. If in doubt, though, I'd try to focus more on:
→ What you enjoy and are most passionate about
→ What subjects, if any, you need as university prerequisites (or what subjects might be useful down the track)
→ If you're so inclined, potentially what you excel at, or what you think will fit best with your other subject selections
