For those who have gotten rejection letters, I've got a good story for you all.
I have a family friend who tried out for MHS year 9 entry last year. He unfortunately did not get in, and didn't get any superiors. He worked really hard during the holidays and got ahead for maths, whilst read a lot and wrote heaps of essays for english. He tried again for year 10 entry and got in with four superiors!
So keep your head high and don't give up. I remember how stressful it was back in my time particularly because within my community it was thought that you HAVE to get into a select-entry school to do well in VCE (unless you can afford to go to a prestigious private school). Let me tell you from my experience, and so many other friend's experiences that it isn't. If it's your first time trying, keep persisting and build resilience, try out for year 10 and year 11 entry. If you still don't get in, remember that you can still do really well in VCE regardless.
