Free Interactive Lessons
Work through a chapter on screen, check your answers as you go, and download a print-ready PDF for revision. No account, no paywall.
Most revision material online is something to read. These are something to do. Each lesson breaks a topic into short sections, and after each one there is a question you answer immediately — a multiple choice, a value to type, an ordering to get right. You find out at once whether you followed it, which is the part that reading alone never tells you.
The answers are all there when you want them: reveal a single worked solution when you are stuck, or open every answer at once when you are revising. There are currently 12 lessons, written for the ICSE syllabus, and more are being added chapter by chapter.
