I'm an ABC, I speak cantonese at home. I did VCE Chinese second language, got 31 raw and enrolled in Chinese 4A. It's not that hard, u just have to be very consistent throughout your studies. I know people that got high 30's and low 40's raw in chinese VCE second language and they struggled with 4A to the point where they dropped back to Chinese 2E. You're there to learn, every class you go to, you're expected to make up sentences on the spot once you learn new vocab or new sentence structure. It's really not that hard, just like everything else, you still need to put in the time and effort, the amount you put in varies with individuals. I can understand why it's competitive since you get people that can speak Chinese brilliantly but just can't read/write, everyone has a weakness. Those that can read/write can't speak well while those that can speak well can't read/write. It's definitely a great subject, you will love Gao lao shi for his jokes. I did Chinese 4A 2 years ago and yet I still look back at the notes that I've used, it's still valuable to me.
