Well, not the worst, but it's certainly the worst in Australia.
For one, most of it only applies within Queensland, so your scores get shitted if you go overseas/to another state.
For two, it's highly dependent on the ability of others (unless you top all of your classes), which pulls you back should they fail.
For three, it's tied into QCS, which is an unfair test in which private schools basically know all the answers before it starts.
*flips tables in homicidal rage*
Why can't everything be individual tests?
I'm a bit fuzzy on what you mean by 1 and 2.
Are you saying that they basically teach you stuff that no one else cares about at the expense of stuff they do?
Are you saying that they pass or fail whole classes at the same time?
And while I'm at it, what's the QCS about?
It's more like the qualification you get (an OP) is less useful once you cross the border. Your OP is also directly linked to your fellow students, because if your class is terrible as a whole (and you don't top the subject), your OP goes down.
Ah yeah, Queensland Core Skills test. It's not very fair, because private schools hire tutors to teach their students how to easily ace the test, whereas state schools are left in the dust. What's more, it's highly dependant on everyone from your school doing really well, otherwise say goodbye to the high-tier OPs.
For someone aiming for a OP 4 (OP1 being the best in a scale of 25), the system is murderous.
Also, interesting to know you're from Queensland.
This means I can stalk you without too much in the way of travel expenses!
...Well, if you'll excuse me, I'm going to get my Class B firearms licence renewed.
