15. Sleep and eat properly
Sleep is more important than you'd imagine — it helps your brain store all the juicy information you've learned throughout the day. Drinking plenty of water and eating healthy foods will also boost your concentration throughout the day.
16. On exam day, make sure you arrive in plenty of time
Nothing adds extra pressure to exam day like the fear of being late. Just make sure you set off at a little earlier than usual. While you wait, if people around you seem stressed about the exam, try to relax and not let their worries affect you. You've prepared well, and you've used all the best Revision Guides money can buy! (Ok, we're done now.)
17. Dress as a medieval knight and demand ale
This is an old tradition, which states that anyone attending an examination in full knight's costume has the right to demand a tankard of ale. Unfortunately, you need to be carrying a sword and if you try this you'll be arrested and sent to prison.
