Most of these responses are incoherent flames or walls of text. Here's the simple rundown:
Subjects are designed to test students' intellectual capabilities rather than to give them useful knowledge for the future.
BoS doesn't give a flying f* whether you're going to use their syllabus information for future reference, as long as they can rank you against other students in the state, its all cheese and crackers for them.
English haters
Most of you are the ones that suck at English. Yes it's true, most English aspects (denoting a text, finding out what Shakespeare REALLY means, etc) are completely useless in future life. Still hating? YOU LIVE IN AN ENGLISH SPEAKING COUNTRY. DEAL WITH IT.
(Edit: without English, Asians would dominate the Australian education system way harder than they already are at the moment)
Math haters
Most of you are the numerically illiterate, hating the concept of using logic to overcome a problem. Yes it's true, you don't need to find the gradient of a curve or know the area of a segment in future life, but as mentioned before, it demonstrates your capabilities and limits. Still hate it? Quit the subject.
Summary? QQ. If you're crying about how hard a subject is, its most likely that hundreds of students around the state are having the same problem.
