Figure 10From: Resitting a high-stakes postgraduate medical examination on multiple occasions: nonlinear multilevel modelling of performance in the MRCP(UK) examinations 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.Back to article page
