Wouldn't worry about getting a good study score for next year when it's a Unit 1/2 subject. If there's other classes, I'd find out what could be done about switching into one with a better teacher? If you absolutely can't, trying talking to your year level co-ordinator about any concerns you've got about the classwork and structure itself, but I wouldn't personally attack the teacher, if I were you, mate. Or basically, sure, say he's often late if you have to but don't mutter anything about Buddhist Catholics. And from everything I've ever been told, Unit 1/2 has very little affect on Unit 3/4. At my school, we're encouraged to just skip 1/2 and do 3/4 in Year 11. So if you can't do anything about the class, and you've waited out a term and nothings happened and it's still compulsory next year and you'll have the same teacher, I'd try doing it by correspondence. At least then you'll have a structure to follow, and a lot of it really seems to be memorisation and understanding/analysing/applying the basic concepts, then more memorising, which should be doable via corro.
