This is a bit of a late reply but here are the topics you should revise (some you don't really need):
Motion
Electronics (although this is not really covered in Yr 12, I think it is still important to understand for the content you learn in Units 3 and 4)
My school didn't use a textbook for Yr 11 physics but for Yr 12 it would be good to follow the following dot points from the Yr 11 study design:
Energy from the atom
• explain nuclear energy as energy resulting from the conversion of mass: E = mc2
• compare the processes of nuclear fusion and nuclear fission
• explain, using a binding energy curve, why both fusion and fission are reactions that produce energy
• explain light as an electromagnetic wave that is produced by the acceleration of charges
• describe the production of synchrotron radiation by an electron radiating energy at a tangent to its circular path
• model the production of light as a result of electron transitions between energy levels within an atom.
Hope this helps and good luck!
