Grade Boundaries

A reminder that IB grades are calculated by taking a weighted average of the raw grades from each assessment. Another way to look at it is that the you accumulate marks from each assessment. The IA is worth 25%, so a 15/25 on the IA would add 15% to the final grade.  This would cap the final grade to 90%, because 10% was lost in the IA. The fact that 15/25 is a 6 is nearly meaningless from the perspective of students; its only purpose is to help examiners determine the overall grade boundary. Only the overall grade boundary is used to assign grades 1-7. For BM HL, the May 2018 boundary for a 7 was 66% overall.
