here is a list of some of the distance education centres for NSW
Distance Education Centres (definitely recommend looking at this website as it has a downloadable pdf on everything you should know about de)
From my knowledge there are only 8 in total that offer this service in NSW
if your too lazy to look here are some direct links:
1.
main page
2.
Karabar
3.
Open High School (i'm pretty sure they only do languages)
4.
Sydney Distance Education High School - Website Home
5.
Dubbo School of Distance Education
i'd try to get in touch with which ever one you want asap, i do recommend karabar though, like i said before, the teachers teach at a 'real' school as well so they have realistic expetations. Plus i know that they do take latecomers (i started in wk 5 or 6).
Sorri if ive said this to you before but hope it helps.
