Seriously guys, stop stressing about year 12, it is not as bad as it is made out to be.It's sad to hear comments like 'im scared shitless' 'its so scary', 'hello pain and stress' because you really shouldn't feel that way.
In all honesty i think year 11 is harder than year 12 due to the transition in workload from year 10. Year 12 is just like an extension of year 11 with the HSC at the end. It's surrounded by this ridiculous hype that it it is the ultimate test in willpower, nerves, discipline etc and causes unbelievable amounts of stress and panic. This is simply not true, your HSC year will only be as stressful as you decide to make it. It is not easy as such, but it is nowhere near as bad as is made out.
And please don't think of the HSC exams as this super difficult obstical to overcome, they teach you everything you need to know to do them and by the time you get around to doing past papers its like 'hey, i can actually do this, i know the answers, this really isnt so bad'.
