exactly what shellybelly said! YEAR 12 WAS THE BEST! I don't regret a moment of it! It was just awesome, despite all the stress. Sure i could have worked harder, but whatever the hell i did when i was should have been working was way more fun!
Lifes too short to stress! Just do the best with what you've got, don't live in the past, try harder the next time, and get on with your life.
Everyone enjoy post HSC life, but don't lose touch with your friends. And whilst moving forward, don't ever forget where you came from.
