Before you start, please ensure that you've taken the Intro Quiz and Bronze quizzes.If you have not completed them then we won't be able to reward you for completing this one.

Anyway, relax and have fun; it'll only take about 10 minutes and if you don't succeed the first time, just give it another go. There is no limit to the number of times that you take this quiz, and as they say; practice makes perfect.

NOTE: Please ensure that you enter your details correctly. Your name will displayed on the certificate (as entered here) and your giffgaff member name will allow us to know who took the quiz. Good luck!
