9. Plan your exam day
Make sure you get everything ready well in advance of the exam - don't leave it to the day before to suddenly realize you don't know the way, or what you're supposed to bring. Check all the rules and requirements, and plan your route and journey time. If possible, do a test run of the trip; if not, write down clear directions.
Work out how long it will take to get there - then add on some extra time. You really don't want to arrive having had to run halfway or feeling frazzled from losing your way. You could also make plans to travel to the exam with friends or classmates, as long as you know they're likely to be punctual!
