Really curious as I want to switch from my school to a better school if possible (Very shit science and english department). Any selective schools in sydney which accept students in year 12?
Yeah not exactly sure, but keep in mind that the environment is going to be totally different, so will you be able to get used to the environment and competition while coping with the pressure of year 12. Anyway, perhaps this could help: https://www.matrix.edu.au/how-to-enter-a-selective-high-school-in-years-8-12/
Also, have you thought of going to a private/independent school, you can find some pretty good schools in the top 40
