z600, WELCOME TO THE BOS FORUMS
from my opinion, SHORE (or known as Sydney Church of England Grammar School, if you really want to get technical) is one of the top elite private schools in Sydney. One of the "top" members of the GPS, they are extremely competitive both academically and sports. Compared to the other GPS schools, its academics is quite good, but it cannot compare with Grammar or Sydney High, but is better than Newington, Kings, St. Josephs and Scots. I put Riverview as its Catholic equivalent, noting that Shore is an Anglican school. Sporting-wise, it is one of the best schools, doing extremely well in Soccer, Rowing, Basketball and athletics.
Shore is, as you would probably know, and as the same suggests, in the North Shore region, overlooking Sydney Harbour Bridge. Excellent views. Therefore, in general, Shore would attract many upper-class, white Anglo-Saxons as its majority of the student body.
one downside of Shore is that it is currently the most expensive private school in Sydney. The tuition fees reach more than $20k a year. add boarding, ur total costs will double or even triple.
of course, this is an opinion only. im sure that there are people who go to shore who lurks these forums, and im sure they are more than happy to assist you.
oh, just one thing: if ur offer was a scholarship, TAKE IT. HANDS DOWN. PERIOD.
