WAEC Chemistry Syllabus 2026/2027 & Texbooks

The WAEC Chemistry Syllabus 2026/2027: covers three main areas: general chemistry principles, chemical processes and reactions, and specific topics like organic chemistry, inorganic chemistry, and physical chemistry. Key topics include atomic structure, the periodic table, chemical bonding, stoichiometry, and rates of reaction. Candidates should also prepare for a practical paper that assesses laboratory skills.

Examination Guides

The examination will consist of three compulsory papers — Papers 1, 2, and 3. Papers 1 and 2 will be taken together in one sitting, while Paper 3 will be conducted separately.

Paper 1 will comprise fifty multiple-choice objective questions based on Section A of the syllabus, which is common to all candidates. The paper will last for one hour and will carry a total of 50 marks. Candidates are required to answer all questions within the allotted time.

Paper 2 will be a two-hour essay paper covering the entire syllabus and will carry 100 marks. It will be divided into two sections, Section A and Section B. Section A will contain ten short structured questions drawn from the common portion of the syllabus (Section A), all of which must be answered for a total of 25 marks. Section B will consist of four essay questions — two from the common portion (Section A) and two from the section of the syllabus specific to the candidate’s country (either Section B or Section C). Candidates will be required to answer any three of these questions, each worth 25 marks.

Paper 3 will be a practical test lasting two hours for school candidates, or an alternative practical work test lasting one hour and thirty minutes for private candidates. This paper will carry 50 marks and will contain three compulsory questions. The questions will assess candidates’ abilities in three areas: one on quantitative analysis, one on qualitative analysis, and one designed to test familiarity with the practical activities recommended in the teaching syllabus.
