You think it's a good competition? I beg to differ.
I sat it for the first time this year (in year 11) and scored 29/30 (which was only a HD on the paper). What did I lose a mark for? Question 6, which I adamantly believe can be debated to be either A or B.
I was quite devastated, seeing as I understood everything conceptually, and it was perhaps taking too deep an insight into the question that stopped me from attaining a perfect score.
It's really funny, because after I completed the test I showed my dad a copy of the paper, and he laughed when he read question 6. I told him that if they took a simplistic approach to the answer that it could cost me getting a prize. And guess what - it did.
Good competitions shouldn't have questions which ultimately penalise students for adopting different philosophies when considering questions.
