1	Boundaries	These boundaries are based on the mean plus 1.25 standard deviations for past papers. (Year to year boundaries are not normally distributed) Note:+1.25s is 90% confindence							Scaling tool	Use this tool to generate boundaries for tests that do not follow the IB format Place the total marks for each section into the white boxes below to generate scaled test boundaries
