About SSS3 Chemistry Scheme of Work

Chemistry is a key science subject that connects physics and biology and drives many technological and scientific advancements essential for academic growth and development.

Chemistry is vital because it forms the basis for further studies in medicine, engineering, pharmacy, and more. It develops critical thinking and problem-solving skills, useful both in scientific research and everyday life. Understanding chemistry enhances your ability to make informed decisions about health, safety, and the environment.

The Lagos State Unified Scheme of Work ensures a standardized and comprehensive chemistry curriculum for SSS3 students, promoting consistency in teaching and learning. It helps SSS3 students meet the academic requirements for WASSCE, prepares them for tertiary education, and supports overall academic excellence and uniformity across the state and the country. Excelling in WASSCE chemistry is important for university admission and scholarships, opening doors to future opportunities.

Assessment Guide

SSS3 students in Nigeria are assessed in Chemistry 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.
