The A-Level language oral exam can be very intimidating, but you need to remember that the examiner is not there to trip you up, he or she want you to do well too! The best way to revise is to draw mind maps of possible questions that might come up and their answers, and get a friend to help you. This makes sure you stay on the topic, saying relevant things, and don'y ramble. Ask your teacher or tutor for some sample practice questions and also revise key structures and vocab, so if your mind goes blank, you still have something to say!
