err I can't say, according to their websites, both Girraween and Penrith have classes open for Year 10, but according to my brother in Girraween (grad 2024), they almost always open a class for Year 11.
Girraween is picky. I got rejected because my "Behaviour Profile for your Year 9 report contains a number of "usually" and "sometimes"."
That was it. But also, Girraween is a better school. If your report is good, and you've studied for HAST, go for Girra.
If you're ready to feel abysmally worthless and that all your efforts consistently add to nothing, go for Penrith!
