Yeah definitely I get what you mean, there is so much content to go through as PD is mostly rote learning but question can be specific and that's what you have to nail. Also, I never learnt much from my teacher (in fact I don't even remember my teacher standing up and writing on the board to teach the subject), everything I have learnt in PD up until now is just by rote learning by myself. So in saying that, is HSC PD like this as well, you don't actually need a teacher to actually teach the course do you?
Everything is basically rote-able and it can only take you so far in this subject- correct me if I am wrong as you people are like 95%+ finished the course haha
