WASSCE Integrated Science (WAEC) is the integrated-science subject of the West African Senior School Certificate Examination, combining biology, chemistry, physics, agriculture, health and environmental science. It is examined in three papers: Paper 1 is 50 multiple-choice objective questions in 1 hour, Paper 2 is an essay/theory paper, and Paper 3 is a practical or alternative-to-practical test. The syllabus is built on five themes: Diversity of Matter, Cycles, Systems, Energy and Interactions. Results use the A1-F9 grade scale, where A1-C6 is a credit pass. This 100-question bank gives original Paper 1-style objective practice with worked explanations across all five themes.

Sample WASSCE Integrated Science Practice Questions

Try these sample questions to test your WASSCE Integrated Science exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following is the correct SI unit of mass?

A.Newton

B.Kilogram

C.Litre

D.Gram-force

Explanation: Mass is the amount of matter in a body, and its SI unit is the kilogram (kg). The kilogram is one of the seven base units in the International System of Units.

2A student wants to find the volume of an irregular stone. Which method is most suitable?

A.Measure its length with a ruler

B.Use the displacement of water in a measuring cylinder

C.Weigh it on a beam balance

D.Time how long it takes to fall

Explanation: The volume of an irregular solid is found by displacement: the stone is lowered into water in a measuring cylinder and the rise in water level equals the stone's volume. This works because the object pushes aside a volume of water equal to its own volume.

3Which sequence correctly lists the steps of the scientific method?

A.Conclusion, hypothesis, observation, experiment

B.Observation, hypothesis, experiment, conclusion

C.Experiment, observation, conclusion, hypothesis

D.Hypothesis, conclusion, observation, experiment

Explanation: The scientific method begins with observation, leads to a hypothesis, which is then tested by experiment, and finally a conclusion is drawn from the results. Each step builds logically on the one before it.

4Which of the following is a characteristic common to all living things?

A.They can fly

B.They respire

C.They have leaves

D.They are green

Explanation: Respiration, the release of energy from food, is one of the basic life processes shared by all living things, along with nutrition, growth, movement, excretion, sensitivity and reproduction. Not all living things fly, have leaves or are green.

5Which of the following is a non-living thing?

A.Mushroom

B.Bacterium

C.Rock

D.Fern

Explanation: A rock is non-living because it does not respire, grow by feeding, reproduce or respond to stimuli. Mushrooms (fungi), bacteria and ferns are all living organisms.

6The part of the cell that controls all its activities is the

A.cell wall

B.nucleus

C.vacuole

D.cytoplasm

Explanation: The nucleus contains the genetic material (DNA) and controls the cell's activities, including growth and reproduction. It is often called the control centre of the cell.

7Which structure is present in a plant cell but absent in an animal cell?

A.Nucleus

B.Cell membrane

C.Chloroplast

D.Cytoplasm

Explanation: Chloroplasts contain chlorophyll and are found in plant cells, where they carry out photosynthesis. Animal cells lack chloroplasts because animals cannot make their own food.

8Which of the following is the smallest unit of an element that can take part in a chemical reaction?

A.Molecule

B.Atom

C.Mixture

D.Compound

Explanation: An atom is the smallest particle of an element that retains its chemical properties and can take part in a chemical reaction. Elements are made up of identical atoms.

9Which of the following is a mixture?

A.Water

B.Common salt

C.Air

D.Carbon dioxide

Explanation: Air is a mixture of gases, mainly nitrogen and oxygen, that are not chemically combined and can be separated by physical means. Water, common salt and carbon dioxide are pure compounds.

10The three common states of matter are

A.solid, liquid and plasma

B.solid, liquid and gas

C.gas, plasma and liquid

D.solid, gas and mixture

Explanation: Matter commonly exists in three states: solid, liquid and gas, which differ in how closely and how freely their particles are arranged. Solids have a fixed shape and volume, liquids a fixed volume but no fixed shape, and gases neither.

About the WASSCE Integrated Science Exam

WASSCE Integrated Science is the integrated-science subject of the West African Senior School Certificate Examination administered by the West African Examinations Council (WAEC). It combines biology, chemistry, physics, agriculture, health and environmental science into one subject and is examined through three papers: a Paper 1 multiple-choice objective test, a Paper 2 essay/theory paper and a Paper 3 practical or alternative-to-practical test. The syllabus is organised around five themes - Diversity of Matter, Cycles, Systems, Energy and Interactions - so candidates must reason across disciplines, applying scientific methods, measurement and core concepts to living and non-living things, energy, the environment, agriculture and human health. Results are reported on the A1-F9 grade scale, where A1-C6 counts as a credit pass.

Assessment

Three papers. Paper 1: 50 multiple-choice objective questions. Paper 2: essay/theory questions. Paper 3: practical or alternative-to-practical test. This bank focuses on Paper 1 objectives.

Time Limit

Paper 1 lasts 1 hour for 50 objective questions. Paper 2 and Paper 3 are timed separately according to the session's examination timetable.

Passing Score

Graded A1 (Excellent) to F9 (Failure); A1-C6 is a credit pass. There is no fixed published percentage; WAEC sets grade boundaries each session.

Exam Fee

Set by WAEC in each member country and varies by year and candidate type; Integrated Science is one subject within a single WASSCE registration rather than a separately priced exam. (West African Examinations Council (WAEC))

WASSCE Integrated Science Exam Content Outline

WASSCE Integrated Science Study Tips from Top Performers

1Use the WAEC Integrated Science syllabus to check off every topic under the five themes, since Paper 1 can sample any of them across biology, chemistry, physics, agriculture and health.

2Practise the 50-questions-in-60-minutes pace of Paper 1 so you average a little over one minute per objective question and still have time to review.

3Learn the SI units and common conversions (length, mass, time, temperature) because measurement and scientific-method questions appear regularly.

4Draw and label core diagrams - the cell, the digestive and circulatory systems, a food chain and the water and nitrogen cycles - so labelling-style objectives become quick recall.

5Connect concepts to everyday West African examples such as soil and crops, common diseases, electricity safety and the environment, which mirrors how WAEC frames questions.

6Review past-question patterns to spot frequently tested ideas like photosynthesis, acids and bases, simple machines and energy transformation, then drill them until they are automatic.

Frequently Asked Questions

How many questions are on WAEC Integrated Science Paper 1?

Paper 1 is the objective paper and has 50 multiple-choice questions, each with four options. Candidates answer all 50 on a multiple-choice answer sheet within 1 hour.

What are the papers in WASSCE Integrated Science?

There are three papers: Paper 1 (50 multiple-choice objectives), Paper 2 (essay/theory) and Paper 3 (a practical or alternative-to-practical test). Together they assess knowledge, application and practical science skills.
