WASSCE Chemistry is the WAEC senior secondary chemistry exam taken in the West African Senior School Certificate Examination in Nigeria, Ghana, Sierra Leone, Liberia and The Gambia. It has three compulsory papers: Paper 1 (50 multiple-choice objective questions, 1 hour, 50 marks), Paper 2 (essay/theory, 2 hours) and Paper 3 (practical or alternative to practical). The subject is graded A1 to F9, where A1-C6 are credit passes and C6 (about 50%) is the minimum credit most universities require. The syllabus spans atomic structure and bonding, the periodic table, states of matter, stoichiometry, acids, bases and salts, redox and electrochemistry, energetics, equilibrium, and organic and industrial chemistry. This 100-question bank gives original Paper 1-style objective practice across all of those areas.

About the WASSCE Chemistry Exam
WASSCE Chemistry is the senior secondary school chemistry examination of the West African Examinations Council (WAEC), sat in the West African Senior School Certificate Examination across Anglophone West Africa (Nigeria, Ghana, Sierra Leone, Liberia and The Gambia). The subject is examined in three compulsory papers: Paper 1, an objective test of 50 multiple-choice questions drawn from the common Section A of the syllabus; Paper 2, a structured and essay theory paper; and Paper 3, a practical chemistry paper (or the Alternative to Practical Work paper). The syllabus covers atomic structure, bonding and the periodic table, states of matter and gas laws, stoichiometry and the mole concept, acids, bases and salts, redox and electrochemistry, energetics, equilibrium and rates of reaction, and organic and industrial chemistry. Results are reported on the WASSCE A1 to F9 grade scale.
Assessment
Three compulsory papers. Paper 1: 50 multiple-choice objective questions (50 marks). Paper 2: structured/essay theory questions. Paper 3: practical chemistry or the Alternative to Practical Work paper. Papers 1 and 2 are taken in one sitting.
Time Limit
Paper 1 lasts 1 hour and Paper 2 lasts 2 hours (taken together); Paper 3 (practical or alternative to practical) is sat separately on another day.
Passing Score
No separate pass mark for the objective paper. The whole subject is graded A1 to F9; A1-C6 are credit passes (C6 about 50%) and D7-E8 are ordinary passes. Tertiary admission usually needs at least a C6 credit in Chemistry.
Exam Fee
Set by each WAEC national office and paid per full WASSCE registration, not per subject; the fee varies by country (e.g. Nigeria, Ghana) and candidate category and is revised periodically by WAEC. (West African Examinations Council (WAEC))
WASSCE Chemistry Exam Content Outline
Atomic Structure, Bonding and the Periodic Table
Subatomic particles, atomic number and mass number, isotopes and relative atomic mass, electron configuration, the periodic table and periodic trends, and ionic, covalent, metallic and hydrogen bonding with molecular shapes and intermolecular forces.
States of Matter, Gas Laws and Kinetic Theory
Properties of solids, liquids and gases, the kinetic theory of matter, changes of state, diffusion and the gas laws (Boyle's law, Charles's law, the general gas equation and the ideal gas equation).
Stoichiometry and the Mole Concept
Relative atomic and molecular mass, the mole and the Avogadro constant, molar volume of gases, empirical and molecular formulae, mole-ratio calculations from balanced equations and concentration of solutions.
Acids, Bases, Salts and Solubility
Properties and strengths of acids and bases, the pH scale and indicators, neutralisation and acid-base titration, types and preparation of salts, water of crystallisation, deliquescence and efflorescence, and solubility.
Redox, Electrochemistry, Energetics and Equilibrium
Oxidation numbers, oxidising and reducing agents, electrolysis and Faraday's laws, electrochemical cells and the electrochemical series, rates of reaction and collision theory, chemical equilibrium and Le Chatelier's principle, and enthalpy changes.
Organic and Industrial Chemistry
Hydrocarbons (alkanes, alkenes, alkynes), alkanols, alkanoic acids and esters, addition and condensation polymers, and industrial processes including the Haber and Contact processes, extraction of metals, hardness of water and environmental chemistry.

Which countries take WASSCE Chemistry?
WASSCE is administered by WAEC in its member countries: Nigeria, Ghana, Sierra Leone, Liberia and The Gambia, both for school candidates and private (GCE) candidates.
Does Paper 1 cover the whole syllabus?
Paper 1 is drawn from Section A of the syllabus, which is common to all candidates. The objective questions can test any topic in that common section, from atomic structure to organic and industrial chemistry.
Are these official WAEC past questions?
No. These are original OpenExamPrep questions modelled on the WASSCE Chemistry syllabus and Paper 1 objective format. WAEC publishes its own past papers and syllabus separately.
