How much preliminary physics knowledge do we need to retain for the HSC? (1 Viewer)

[darkcounty]

I've heard some people say that preliminary physics isn't that relevant to HSC physics. Like, how most of the historical parts are omitted, you don't need to know how CDs/DVDs and GPS work and you only need a basic understanding of how a circuit works for electricity.

Can anyone confirm/ deny this and what do we actually need to keep for next year?

That advice is pretty much correct but I think you also need to know the basics of interference and diffraction and how this is a wave property and also you definitely need to know about electric fields and magnetic fields but you do go over this again so I wouldnt worry too much
