its good this year the creative writing wasn't so "straight forward" so that people had to think on their feet.
if you tried to write out a memorised creative on your personal reflection to visiting the corner shop and its ramifications you would've been PRETTY screwed. haha but then again i memorised a short story on an old man reflecting so that was awesome and fit perfectly.
basically memorised creatives can help you, but you might need to do 8 or so various plots with different personas (i.e. first, second, third person, a woman, an old man etc..) to be completely confident before entering the exam because they seriously can throw anything (like this year's hmm)
