-I am not familiar with the VCE study design any more
-It would be good to have some idea about Young's double slit experiment and the photoelectric effect experiment. This means that you know the basic jist of what goes on. It does not mean you know perfectly the RL experiment set up. I don't think anything else is covered in physics but then I don't remember, also I am speaking from an old study design viewpoint
-You need to know the conclusions deduced from them
-Can't remember about wordyness but I think it has similar amount of calculation vs writing questions as other sections
At least your book mentions this is quantum mechanics!!!! I only learnt of that word late this year

(I had the nelson book btw). You have discovered the most annoying part of VCE - you only need to know w, x and y, thus I will not teach you z. It's so great to be out of there
