I contacted Uni about my enrolment and I am enrolled, but they didn't have any of my unit choices. Even though I remember filling the form in for them. So I did that over the phone.
The choice is either Database & Analysis (evil) or Artificial Intelligence (something I haven't done before). I have no idea what the database module covers, but I know for AI you work in a group to program a little robot with AI, so it can find it's way through a maze (sounds like fun I know).
