Craig’n’Dave create GCSE, IGCSE and A Level Computer Science videos for students and teachers, covering all required content for the major UK exam boards. Our videos are ad‑free, sponsor‑free and ideal for Computer Science revision, exam preparation and classroom use. Craig and Dave are experienced Computer Science teachers in England, teaching since 1997. Both have degrees in Computing and industry experience as programmers, bringing real‑world understanding to Computer Science topics. Alongside our core Computer Science courses, we also publish Knowledge Byte videos with Kat (“The Lesson Hacker”), exploring interesting areas of Computer Science beyond the exam specifications. Our videos are widely used for flipped classroom teaching, independent study and subject knowledge enhancement. GCSE videos include optional prompts for Cornell note‑taking, with this support removed at A Level to develop the independent learning skills needed for university and careers in computing.
