Join Richard Vaughan as he attempts to unpick the changes to GCSEs and A-levels brought in this month by the government. He hears from resident TES curriculum expert William Stewart, who gives an overview of the exam reforms. He catches up with John Blake, a history teacher at a London comprehensive, to get a teacher's perspective on the changes. And, finally, he hears from Geoff Barton, head of the King Edward VI School in Suffolk, to hear how the overhaul will impact on school leaders.
