Figure 10.

Shows the expected behaviour at each attempt, based on the fitted negative exponential model, M3, of candidates whose mark at the first attempt at Part 1 varies from 30 marks below the pass mark to 25 marks above the pass mark. Note that the maximum levels and the rate of increase co-vary both with the starting level and with each other. The red horizontal line is the pass mark.
