You have to prepare a session on any topic or you can choose from given topics. You are in a room with three other applicants and the person holding the session. Then, you teach about any topic for a few minutes, as if you were tutoring someone. They tell you a little "how-to" beforehand. As long as you are interactive and remember their tips, it should be easy.
