Try and be as relaxed as you can. A little bit of nerves can help to keep you alert. Don’t believe any stories you hear about "they only pass people on a Tuesday" or "the quota for this month has been reached".

Here are some tips to help you on the day:

• Make sure you get a good night’s sleep.
• Don’t drink too much the night before.
• Don’t take pills to calm you as they may make you react slower.
• Think about where you'll be driving and the important points to remember.
• A positive attitude will help but don’t be too cocky.
• Make sure you don’t need the toilet, food or water.
• Take a few deep breaths.
