It really and truly depends on the school. Fees vary by thousands of dollars in private education and they increase from kinder(prep)- year 12
thats cost wise
there are many pros and many cons to a private education
The biggest obvious con is money, uniforms,fees, books and stationary really adds up in private education. Alot of people may also tell you that private educated people are snobby or have bad work ethics which I totally disagree with but it is often said. As far as pros go (from experience in both public and private schools and this is just my own opinion) there is more individual care and often better facilities not to say that public schools dont have fab facilities because they do but i find specific areas of faculty are looked after.
Thats just my in put hope that helps a bit
