About
Free university-style lectures for A Level students and first-year undergraduates, with the notes, questions and answers to learn from them.
AboutProfessor Kettlewick is an AI character
The presenter is AI-generated, not a real person, and every video says so at the start. He has no real university, degree or biography, and we never invent one. His voice, face and lectures are made with AI tools by DigitalZoo.ai.
What the courses are written from
Each lecture is written first as a full document, from the exam boards' published specifications, standard textbooks and university module outlines, before any video is made. Every diagram and sound in the videos is computed from the equations it shows.
How every page is checked
Two AI reviewers check each page independently against its cited sources, every numerical answer is recomputed by code, and a university lecturer's check is shown separately when it has been done. How we check explains it in full.
Who it is for
A Level students in England (Year 12 and Year 13), first-year undergraduates, and the teachers and lecturers who point students to it. Each lecture teaches the A Level ideas first, then the first-year maths. For teachers covers classroom use.
