This Practice Test Stories Competition is run by Cambridge University Press and Cambridge English Language Assessment.
If you've used any of their practice tests to improve your exam result and it changed your life in a way, upload either your written story (up to 100 words) or your video story (of up to 2 minutes) for a chance to win an iPad mini.
You must be over 18 to enter the contest or over 13 and have your parent and guardian's consent.
One winner will be chosen based on the credibility of the story, the compelling nature of the story and the perceived English language level of the entrant.
The contest will close on 30th April 2015, 08.00 BST.
