i got 14/15 in the trial for this bit, and my creative writing skills are about .01 out of 10.
basically what i did (and my teacher told me this is prob what got me the marks) is i used LOTS of similes, metaphors, rhetorical questions, etc. we had a newspaper article talking about the pros and cons of technology, and my entire thing was basically all rhetorical questions.
thats pretty much what their looking for (use of similes, metaphors, and pretty much anything like that) and even if your ideas and writing are shit you will do reasonably well
