hi mrkebiny,
thank you! well basically, i knew that i would never beat chinese background students by raw ability, so i focused on memorising a lot! and i memorised SMARTLY, not unnecessary things that were sure not to be examined. i found this the best and while, in the end, the exam topic wasn't something i'd prepared, i was able to mould all the stuff i memorised into something good

also, make sure you learn lots and lots of idioms. i'm actually selling a list of the most useful idioms i used, if you're interested PM me.
hi splash-tackle-flail,
my general conversation was about 15000 characters and my detailed study was also about 15000 characters. now i had about 100 idioms in each of them... so i was scared that the examiners would ask me "what does this idiom mean?" so i also memorised definitions for each of the idioms i used (... unfortunately the examiners never asked me that haha). yeah those were the questions i used plus i added my own. you have to think of follow-up questions to your answers. for example, if they gave you a standard question like 'what do you want to be in the future' and you give your response, they could follow up with 'what are you currently doing to achieve it' (i got this question in the oral... luckily i had prepared for it!). to prepare for the oral, i did heaps and heaps of practices. well, first i wrote my entire script and memorised it and then slowly started to practice with my teacher and tutor. i would get stumped LOTS because they would ask me a question i hadn't memorised and i wasn't able to speak fluently when i had to respond to a question i hadn't prepared for... so i would write down each question they stumped me and memorise responses to those. eventually, there were pretty much no more questions that stumped me. also, i did a couple of REAL practice orals (like same conditions, real oral examiners etc.) and got feedback which helped to improve because i would get quite nervous - it reciprocated exam conditions! i would do chinese almost every day. i would try to write maybe 2-3 essays a week, perhaps more. sometimes, when i was really into it (e.g. for an upcoming SAC), i would write 5-7 essays in a day... but yeah. i would also be continuously going through my oral and making sure it was memorised. i remember that it took me about 5 hours just to go through my entire script to ensure it was all memorised... so long but it paid off. also, whenever i got an essay topic, i would type it in google and read articles about it and copy their language (because it was much better than mine!). that helped me learn new and relevant vocabulary

haha thanks!
