Thanks, what chinese websites would you look at on the Internet? Would you search all the characters definitions that you didn't know?
Also, are the general conversation questions on the VCAA website?
the most important thing is to read articles that are relevant to what you are learning. so i would normally write an essay on a specific topic, and then after writing the essay, i would look up articles about that same topic online and learn any good vocabulary these articles had. i found this helped a lot, particularly with idioms. in regards to searching all character definitions, i was normally able to get a gist of what the sentence/paragraph was trying to say. i would then see if there was any idioms/advanced language/advanced sentence structures that they used and look at the meanings of those and see if i could use them myself.
for the general conversation questions, your teacher should give you a list (or if you go to XJS you will get a list). if you have friends who have done it previously, they should have a list too. however, VCAA does not give us a list. so the list that you get is the MOST COMMON questions that they could ask, but certainly not all of them. i'm pretty sure a long time ago i posted the list up, so maybe you can find that.
hope that helps! thanks, drake
