Hi! I'm afraid the exam isn't working yet. It'll be there in a future build - I'm updating the game every month or there abouts, but i'm focussing right now on getting the Heather and Jennifer storylines up to the games done. The exam will happen on the morning of the same day you perform in the games, so that will be up and running before Chapter 6. It's going to be its own mini-game, so it'll take me a while to get it up and running.
