Every concept has an interactive simulation — adjust variables in real time and watch physics happen. Wave equations, ray diagrams, lens behaviour — all live.
Examiner Intelligence
Every topic includes exactly what Cambridge examiners penalise, the precise mark scheme wording required for full marks, and common mistakes from 25 years of marking.
Live Classroom Annotation
Write and draw directly over any page using a pen or Apple Pencil — ideal for annotating diagrams and simulations during live lessons.
