It provides essential concepts, facts, explanations, illustrations, and exercises that help students achieve expected learning outcomes.

It ensures continuity, uniformity, and standardization in education across institutions. Teachers rely on textbooks for lesson planning, while students depend on them for comprehension, revision, and examination preparation.
