FCE

I've found these video samples of Cambridge First Certificate Exams. The level is a bit lower than the B2 level you should master at the end of your advanced2 course, but it can be an example to help you out to prepare some topics and dialogues for the oral tests. You can always listen to them, take notes and try to improve them as well as trying to correct any mistakes the candidates make. It's authentic material. We don't know if those candidates passed the exam or not, so be careful with that. It should be better to take a kind of critical position and use them as an exercise to practise and improve your performance.
