The National Parent Fo
rum of Scotland has produced Revision in a Nutshell guides for the new Highers (20 subjects) and updated Revision guides for National 5s (20 subjects). These revision guides contain direct links to SQA specimen question papers, exemplar question papers plus past question papers, where appropriate. The guides advise learners to check with their teachers to make sure that material is relevant. The guides are primarily intended to provide the SQA direct links by subject in one place, and to give some additional revision opportunities.
