This WAEC Chemistry Syllabus 2025/2026 is designed specifically for examination purposes, with the topics arranged in a manner suited for assessment rather than teaching. The syllabus assumes that candidates have completed the Integrated Science, Basic Science, or General Science, and Mathematics syllabuses at the Junior Secondary School (JSS) or Junior High School (J.H.S) level.

It also assumes that candidates will actively engage in suggested activities and project work to develop the necessary competencies and skills outlined in the relevant Chemistry teaching syllabuses. Additionally, the syllabus presumes that the schools offering the subject are equipped with well-maintained laboratories.

Candidates are expected to have a basic understanding of significant figures, S.I. units, and the conventional/IUPAC system of nomenclature. The examination consists of three papers: Paper 1, Paper 2, and Paper 3, each serving a distinct purpose. Paper 1 consists of fifty multiple-choice objective questions drawn from the common sections of the syllabus. Candidates must answer all questions within one hour, with a total of 50 marks.

Paper 2 is a two-hour essay paper covering the entire syllabus and carrying 100 marks. It is divided into two sections: Section A consists of ten short structured questions based on the common portion of the syllabus, for which candidates must answer all questions worth 25 marks. Section B contains two questions from the common portion and two additional questions from sections specific to the candidate’s country. Candidates must answer any three of these questions, each worth 25 marks.

Paper 3 is a practical test designed to evaluate candidates’ hands-on skills. It is a two-hour test for school candidates and a 1-hour 30-minute alternative for private candidates. This paper consists of three compulsory questions and carries 50 marks. The questions include one on quantitative analysis, one on qualitative analysis, and one on the practical activities suggested in the teaching syllabuses, allowing candidates to demonstrate their familiarity with laboratory practices.

The continuous assessment component of the examination will be detailed separately by the Council. This syllabus emphasizes the importance of a comprehensive approach to learning, ensuring that candidates are well-prepared for both theoretical and practical aspects of their studies.

WAEC Chemistry Syllabus 2025/2026

The latest WAEC Chemistry Syllabus 2025 are essential resources for students preparing for the West African Senior School Certificate Examination (WASSCE). These syllabi serve as detailed guides, outlining everything students need to know about the subjects they are registered for. They help candidates navigate the exam by offering specific, organized, and clear instructions, effectively acting as a communication tool between the West African Examinations Council (WAEC) and the students.

A key reason for the poor performance in WAEC exams is students’ lack of awareness about common pitfalls, incomplete syllabus coverage, and unfamiliarity with the test format. This insight into exam challenges has led to a focus on better preparation, encouraging students to thoroughly understand the exam structure and content.

Rather than relying on shortcuts like exam “expos,” students are encouraged to study the syllabus and use the right materials to prepare. To assist with this, syllabi for major WAEC subjects such as General Mathematics, Biology, Chemistry, Physics, Literature, Economics, and others have been compiled. This ensures that candidates for various WAEC sessions—May/June, Jan/Feb, and Nov/Dec—are well-equipped to excel.
