BIOLOGY SYLLABUS

Making syllabus available to candidates is another way of examination helping them to prepare adequately for external examination. Syllabus comprises all the topics that will be look into when constructing questions for the examination. So as candidates, it is pertinent for you to have and use these syllabus to study. Below is the WAEC Syllabus for biology as regards the 2023/2024 WAEC examination. Endeavor to digest every content in it.
