Stace, the HSC is so far from the most important time in your life, its a joke to hear they still say that. For me, I thought the HSC was like the end of the world, that if I failed my expectations that would be it. I far exceeded my expectations, and here I am sitting on my butt 4 years later with no clue as to what I want to do with the rest of my life. School is not the be all and end all, there are so many more years of your life that will be far more important, and there are so many more possibilities out in the big wide world. If I can offer you any advice, just enjoy school, cause the relationships you have with your friends and teachers will never be repeated on the same level again.
I am so over work at the moment, I feel like bashing my head against a brick wall. The end.
