Understanding the WASSCE Science Syllabus
The WASSCE Science syllabus is designed to assess students’ understanding of fundamental scientific principles and their application to real-world scenarios. The syllabus covers a wide range of topics across different scientific disciplines, including Biology, Chemistry, and Physics. Each discipline has its own set of subtopics, and students are expected to demonstrate a comprehensive understanding of these areas.
The examination is structured in a way that tests students’ ability to recall knowledge, apply concepts, analyze data, and solve problems. Questions can range from simple recall questions to more complex problem-solving scenarios that require logical reasoning and critical thinking skills. It is important for students to familiarize themselves with the syllabus and structure of the examination to effectively prepare for the challenges they may encounter.

Tips for Answering WASSCE Science Questions
Successfully tackling WASSCE Science questions requires a combination of strong knowledge, effective exam techniques, and time management skills. Here are some essential tips to help you excel in the examination:
- Thorough Understanding of Concepts: Focus on understanding the underlying principles and concepts rather than just memorizing facts. This will allow you to apply the knowledge to various situations and answer critical thinking questions.
- Practice, Practice, Practice: Solving past papers and mock exams is crucial. It allows you to familiarize yourself with the format of the examination, practice time management, and identify your strengths and weaknesses.
- Effective Time Management: Allocate specific time to each question based on its complexity. Don’t spend too much time on any single question.
- Read Questions Carefully: Pay close attention to the specific instructions and wording of the questions. Avoid making assumptions and focus on providing precise answers.
- Organize Your Answers: Structure your answers clearly and logically. Use diagrams, graphs, and tables to illustrate your points effectively.
- Review Your Work: If time permits, take a few minutes to review your answers and correct any errors. Make sure you have answered all parts of each question.

Analyzing WASSCE 2018 Science Questions
To gain deeper insights into the WASSCE 2018 Science papers, let’s analyze some of the common question types and their respective answers. Keep in mind that this is not an exhaustive list but rather a selection of illustrative examples to provide a clearer understanding of the exam’s approach.
Biology:
Question: Describe the process of photosynthesis and its significance for life on Earth.
Answer: Photosynthesis is the process by which green plants and some algae convert light energy into chemical energy in the form of glucose. This process takes place in chloroplasts, which contain chlorophyll, a green pigment that absorbs sunlight. The overall equation for photosynthesis is:
6CO2 (Carbon dioxide) + 6H2O (Water) + Light energy → C6H12O6 (Glucose) + 6O2 (Oxygen)
Photosynthesis is crucial for life on Earth as it is the primary source of energy for most living organisms. The glucose produced during photosynthesis provides the energy needed for plant growth, development, and reproduction. The oxygen released as a byproduct is essential for respiration in both plants and animals.
Chemistry:
Question: Explain the difference between a strong acid and a weak acid and provide an example of each.
Answer: A strong acid is an acid that completely ionizes in solution, releasing all its hydrogen ions (H+). Examples of strong acids include hydrochloric acid (HCl) and sulfuric acid (H2SO4). Weak acids, on the other hand, only partially ionize in solution, releasing a limited amount of H+ ions. Examples of weak acids include acetic acid (CH3COOH) and carbonic acid (H2CO3).
The difference in ionization behavior between strong and weak acids arises from their structure and the strength of their bonds. Strong acids have weaker bonds holding their H+ ions, making them more likely to release them into solution. Weak acids have stronger bonds, leading to less ionization. The degree of ionization plays a significant role in the acidity of a solution, with strong acids being more acidic than weak acids at the same concentration.
Physics:
Question: A car travels at a constant speed of 20 m/s for 10 seconds. Calculate the distance covered by the car.
Answer: The distance covered by the car can be calculated using the formula: Distance = Speed × Time
In this case, Distance = 20 m/s × 10 s = 200 meters.
Therefore, the car covers a distance of 200 meters in 10 seconds.
