The practice interface offers Algebra, Number, and Geometry, with controls for writing, checking, undoing, and clearing work. The planned scope covers AQA, Edexcel, and OCR at Foundation and Higher tiers; a weekly parent-report preview is still labeled as being built. The site says it will publish how often its marking agrees with an examiner before launch.
