Year 11:
Module 2 (if done properly)
The rest
Year 12:
Module 6 (some tricky calcs and all the theory needs to be understood, not just remembered)
Module 8 (Pretty much pure rote learning and I hate rote learning)
Module 7 (similar to Mod 6 -- a bit more rote learning tho, calcs are easy but special relativity as a concept will do your head in)
Module 5 (just maffs)
