i dont see how the difficulty can change each year.
1. text response: If you know your text well enough and have prepared yourself = no question should be hard. Even if it is retarded and what not, if other people can and did do them, then so can you. Also, if it really was that bad (as people have suggested for LBW) then everybody will do badly, causing the system to still be as equal if everyone did well.
2. Creating and presenting: This just comes down to preparation. I wrote 2 practice pieces, and that was it. Fortunately for me it was identical to the one on the exam.
3. Language: No matter what subject the article was written in regards to, it is simply words on a page. And VCAA always chooses articles with many things to analyse... only issue i can think of was the amount of unnecessary detail in the background info... it has never been so detailed which wasted time for me.
So i think its a bullshit article, how can you say OH HEY THIS YEARS WAS EASY, no dickhead, you were prepared/just smart. Every year its the same thing (basically.)
