1. Introduction
The WAEC Biology exam assesses understanding of life sciences through theory, practical skills, and data interpretation. Excelling requires mastery of cellular biology, ecology, physiology, and genetics alongside strong laboratory techniques.
This guide breaks down the syllabus, deciphers common question formats, and presents targeted strategies for diagram labeling, experiment questions, and terminology recall. You’ll learn to balance memorization with analytical skills and optimize your performance under exam conditions.
We’ll also highlight high-yield topics, recommend quality resources, and propose practice routines to ensure you enter the exam hall fully prepared.
