Just to show my credentials, I wenr from a Mt Druitt public primary school, to Penrith, to Girra, then on to Northmead High then Year12 at Tafe.
Tafe is by far the best learning environment of them all. It is no BS fast paced teaching with total freedom. You cover so much more so much quicker, yet I never felt as if i was being overloaded with work. In retrospect much time was wasted in regular schools. In such an environment you don't have people working in competition with eachother, but everyone seems to be concerned more with outdoing themselves rather than eachother. The freedom also means anyone who isn't realy serious about study drops out very quickly or never shows up, this accounts for about 75% of all the people who go.
But, by and large, Penrith was a pure joy to go to, the people there all got along so well, and were all quite friendly, and above all hilarious. My time there consisted of constant laughing. The teachers were no better than anywhere else though.
Penrith though, is different to most selectives, while it has its fair share of good marks (bar the 2002 marks, but I was good friends with the people in that grade and they were all massive stoners, hence the low ranking that year) I didn't find it at all competetive, the people while incredibly clever (moreso than Girra) where very laid back and hence intelligent conversation and learning opportunities were had, but this was usually irrelevant to classwork.
Northmead sucked, it had some utterly brilliant teachrs though, and if you wanted to learn you could do very well. The people there were real nice aswell, depsite what would be expected (well at least to me). The place was whorishly underfunded though, it was less than half the size of Penrith and was very shoddy looking.
Girra on the other hand, was quite different to Penrith, nowhere near the fun, much more competition, nowhere near as interesting. Altogether it gets my vote for worst school I have been to.
Penrith is my 1st choice, it was just that much fun, but aparently these days it isn't anywhere near as good as it used to be. The class of 2002 and 2003 where the spirit of that place.
Tafe is the best one for actual education, I don't think anything comes close, selective or no. The teachers I had for Tafe were all of a very high caliber.
In conclusion, selective schools do not have the best teachers, they may not even have the best learning environment, what they do have is the brightest kids to begin with, and that counts for ALOT. Take it from me, I got a 62 UAI last year, when I got the result I was shocked, I didn't deserve 62, I did NO work and left all my exams 1hour in, I was pulling 30% for assignments (ie merely attempting them) yet I still beat the majority of the state. Being incredibly lazy yet a bit clever (i am about as stupid as a selective student gets) can take you VERY far. Classmates who studied and worked many hours got far less, hence, getting the more gifted students will account for the vast majority of the results of selective schools.
