About SSS3 Biology Scheme of Work

Biology, the science of life and living organisms offers deep insights into the natural world and its processes. In this final year of secondary school, SSS3 students learn about the complexities of life at various levels, from molecular biology and genetic inheritance to the principles of evolution and ecosystem dynamics. They also study the intricate systems that sustain human life.

The Lagos State Unified Scheme of Work for SSS3 is thoughtfully structured to provide a thorough understanding of advanced biological topics. This scheme of work covers a broad range of subjects, including genetics, evolution, ecology, and human physiology, all of which are vital for students’ academic growth and practical knowledge.

The  Lagos State Unified Scheme of Work places a strong emphasis on practical skills, encouraging students to conduct experiments and make observations, thus fostering scientific thinking and problem-solving abilities.

The significance of SSS3 Biology is immense, particularly in relation to the WASSCE. A solid grasp of this subject is essential for achieving excellent scores in the examination, which is a stepping stone to higher education and numerous career opportunities particularly for students aiming for careers in medicine, nursing, pharmacy, environmental science, biotechnology, and health-related fields

Assessment Guide

SSS3 students in Nigeria are assessed in Biology through continuous assessments and the WASSCE. Continuous assessments include class tests, assignments, oral presentations, projects, and class participation. The WASSCE consists of multiple-choice questions, essays, and practicals. These assessments evaluate a range of skills, ensuring holistic evaluation, skill development, preparation for higher education and careers, and identification of areas for improvement.
