I wouldn't worry too much about it. As long as you're on top of things, it's completely attainable. During the student tour, the tour guide mentioned that everyone takes the individual assessment which is a pass at 90%. Then we take the same exam as a group. If the group exam is higher than 95%, then you only need 85% on your individual assessment to pass. If you fail on Friday (test day), you get reassessed the following Monday. If you fail the reassessment, then you have summer school. The information packet mentioned that only 2% had to withdraw for academic reasons since 2003.
