36-Week WAEC Revision Programme — Business Studies (IGCSE)
September to the May WAEC sitting. SS3 is not a year of new material so much as a year of pressure on material already met, so this is not a course to work through from the beginning — it is a testing programme. Each week you answer cold, work the ones you got wrong, and have the AI explain why you got them wrong. Anything you turn out never to have been taught, you learn there and then, and meet again three weeks later.
A week is one block of the syllabus and the prompts that cover it. You are not meant to do all of them: answer the questions first, and let what you get wrong decide which of the rest you need. Fifteen or twenty minutes a subject is a real week's work — nine subjects do not fit any other way.
Every week, in this order
Start with the questions, not the explanation. The first two steps are in every week; a purpose-written mistake or pitfalls prompt appears in about half of them, and where it does not, your own wrong answers are the material for step three.
- 1. Retrieve — Answer cold, with nothing in front of you. Wrong answers are the point — they show you where the week's work is.
- 2. Drill — Work the ones you missed properly, showing every step, so you and the AI can both see where it went wrong.
- 3. Explain my error — Ask why your answer was wrong, not just what the right one is. Where the week offers a Spot My Mistake or WAEC Pitfalls prompt, use it.
- 4. Teach me — Only if the error turns out to be something you were never taught. Then come back and retrieve it again.
