How we prepare our lesson notes

Each note covers one topic for one class and one term, and the notes are arranged in teaching order. Every note has behavioural objectives, the lesson content in short sections, evaluation questions and an assignment drawn from the same note.

Before publication, the notes are edited for accuracy, plain language and the right level for the class. Teachers can use them as a base for lesson planning and adapt them to their own pupils and school resources.

Every note is free to read online. A PDF or Word copy of one subject costs ₦1,000 for one term, or ₦2,000 for all three terms. If you find a mistake, tell us and we will correct it.
