Each lesson’s readiness = video watched (20%) + best multiple-choice score (40%) + self-marked structured answers (40%). Paper 1 readiness = content lessons (50%) + Paper 1 mock (30%) + lesson E1 (20%). Paper 2 = content lessons (60%) + Paper 2 mock, lesson E2 (40%). Paper 3 (SBA) = SBA project lessons (60%) + Paper 03 and Paper 032 lessons E3–E5 (40%). Overall = Paper 1 × 30% + Paper 2 × 50% + Paper 3 × 20%, the same weights as CSEC Additional Mathematics (30 / 50 / 20). Progress is saved in this browser only.

How to use this library

  1. Go in order. Start at A1. Later lessons build on earlier ones (for example, the calculus lessons use the rules of indices from A8).
  2. Watch the video with sound on, or switch to captions. Pause and try each worked example yourself before the answer appears.
  3. Write the key notes and formulae into your notebook, and redo every worked example without looking.
  4. Do the practice honestly. Work on paper, answer before checking, and self-mark strictly — CSEC examiners give method marks only for working that is clearly shown.
  5. Watch your readiness. Anything under 75% goes on your revision list. Return to it after a few days.
