I've done many exams over my life, and here is my advice:
Study well in advance, so that you know the material inside out.
Have a big bottle of water with you.
Eat well before the exam.
Have a good night sleep before.
If you drink coffee, have a coffee or energy drink before hand.
Sorry dude, there is no magic solution to acing an exam than hard work. I have used amphetamines and ritalin for completing assignments, but i wouldn't of needed to do this if I hadn't left them until the last minute. As someone mentioned before, it can make your thought processes too scattered. Your HSC is too important to risk it. Just study hard. Save it til after your done and you can snort as much speed as you want.
