Remember everyone, this is it. In one hour will come the marks which will solely define who you are and what you become. Succeed, and prosper. Fail, and live a life of failure and dissapointment.
Except that the above is really a load of tripe. HSC is just one avenue to success people. Don't worry about it
PS. I'm only staying up because parents are allowing on account of the whole HSC-at-6 thing
