I think the concepts and all that are fine. it's just that physics has extremely vague theory with crap textbooks. So you never know what you actually need. But for chem, it's a lot better
And bio is simply concept-less imo, just pure theory and annoying ness. IMO
The reason some HSC Physics theories are so vague is because the actual theory behind them is far more complicated and mathematical to be understood by a typical HSC student.
Uni Physics is much more mathematically concentrated because you need them to derive rationalise a lot of these results (those of which are "assumed" in the HSC). Some of the classical theories in Physics use vectors and calculus like those you encounter in Extension 2 Maths.
HSC Chemistry also relies on forcing you to just accept the theory without much discussion on where it came from (though not to the same extent as Physics). You have to remember the equations rather than the mechanism behind them, not to mention the ion tests!
Uni Chemistry focuses on HOW reactions occur, which equips you with the skill of predicting products with any given set of reactants by understanding the actual mechanism (electron movements) and thermodynamics (energy levels) of the reaction.
HSC Biology is a very rote-learning type of course. Unfortunately, unless you have some good understanding of biochemistry it's just another course where you have to accept the theory without much derivation.
I'm not sure how uni Biology goes as I have not done it before, but I'm pretty sure that mathematical models are also applied to develop the theory in the first place.
