This lesson has been created to prepare students for their GCSE mocks and public examinations. It is the third lesson in a set of skills lessons which helps them revise and master source utility questions. The lesson starts by explaining how to get full marks on a source utility question, and then solidifies student learning through AFL modeling and repetition. This lesson contains material based on the Weimar and Nazi Germany depth study (USA Conflict at home and abroad also available). It takes about an hour to teach and enables students to practice their source skills.
