I went to Melbourne High and from what I remember of the entrance exam, there were some things that we didn't cover in year 8 that turned up on the exam. Things you should learn are basic trigonometry, pythagoras, ratios and surds. Also, another element of the exam was where they gave you four pictures, and you had to create a story out of them. We had....a flag with a smiley face, a prisoner, a key, and a castle. I remember writing a dreadful story about some guy who had escaped from gaol and had to go to the kingdom of happiness or something. Somehow I got in. Our persuasive piece was about reality TV and the exploitation of its contestants. A tip that I have for you, which is what I did, is to keep a watch nearby. When you see that there are only five minutes left, fill in the rest of your multiple choice sheet, either randomly, or by selecting a single letter. Then, skim through the ones that you had to guess, and pick out what appears easy, and do only them. It'll ensure that you at least get an answer for everything, and that you'll get the easy ones near the end.
