This markbook works well for KS3 as well but I will now use it for the number GCSE number system. Each column works and is RAGged against the target level. It also works so it takes the best performing, composing and listening grade and averages them out to give an overall working at level in the end column. (Really useful for doing reports). Rather than an abc system it works on a 0.2, 0.5, 0.8 system for each grade.
