have read lots about schools in adelaide and as i plan to teach there I wondered if things that i had read like only 15% of students finish high school and only 1% of Adelaide uni students are actually from SA are true??....My son will also be going to high school and lots of people have advised private education although i would want him to go to the local state school in order to make friends in the area and feel part of the community....any info anyone - or insight from teachers, is this the right place to go????
