   Full notes for every spec point: definitions, equations, derivations, worked examples and exam tips.

2. Interactive diagrams

   Simulations you can control, so you can see how each quantity affects the others.

3. Video lesson

   A YouTube explanation for each chapter.

4. Every past-paper question

   All questions on the chapter from June 2017 to June 2026, cut from the original papers.

5. Official mark schemes

6. Practice questions

   Original exam-style questions with full worked answers, plus self-marking multiple choice.

§ Papers

The four written exams

AS = Units 1 + 2. The full A-level adds Units 3 and 4 plus Unit 5 (Physics in practice), which tests practical skills from every topic. The required practicals are covered in the notes for the chapters they belong to.
