Tips for the oral exam

The oral exam is an opportunity for you to demonstrate your knowledge, your speaking skills, as well as your ability to communicate.
Before the exam practice working with classmates or practice in front of a mirror, to evaluate yourself.
Maintain your self-confidence and composure.
If you find yourself anxious, take several slow, deep breaths to relax.
Don't talk about the test to other students just before entering the room: their anxiety can be contagious.
Correct yourself if you make any mistakes.
Keep eye contact.
And remind yourself that you are well-prepared and are going to do well.

The  British Council has published a set of videos explaining what you should and shouldn’t do during a speaking test. Please watch them and take notes, the advice given will probably be useful for you in the future.
