Shows fitted negative exponential curves for Part 1 (blue), Part 2 (green) and PACES (red). The horizontal blue, green and red dashed lines are the estimated maximum (asymptotic) levels for Part1, Part2 and PACES. Note that the three examinations are not on equivalent scales and, therefore, no direct comparison between absolute levels should be made. PACES, Practical Assessment of Clinical Examination Skills.
