Have you ever had to explain how something works or why something happens—without giving your opinion or telling a story? That’s exactly what an expository essay does. The word expository comes from “expose,” meaning to explain, describe, or inform.
In WASSCE, expository essays test your ability to organize facts clearly, use logical reasoning, and write in a neutral tone. This lesson will teach you how to write an effective expository essay by breaking down structure, tone, examples, and practice.
An expository essay is a factual, non-fiction essay that presents information, explanations, or ideas in a clear and logical way. It is not about opinions, stories, or persuasion. Instead, it answers questions like:
What is it?
How does it work?
Why does it happen?
What are its causes or effects?
🧠 Think of it as teaching someone about something they don’t know, like a mini lecture in writing form.
Common types include:
Explanatory Essays: Explaining a process or situation
E.g., “Describe how to prepare for a job interview.”
Cause-and-Effect Essays: Showing how or why something happens
E.g., “Explain the causes and effects of rural-urban migration.”
Comparative Essays: Showing similarities and differences
E.g., “Compare life in the village to life in the city.”
Definition Essays: Explaining a concept
E.g., “What is discipline, and why is it important?”

Time management refers to the ability to plan and control how much time is spent on specific activities. For students, it is one of the most essential skills for academic and personal success. A student who manages their time effectively is more likely to complete homework, prepare for exams, and balance school with other activities. Poor time management often leads to stress, missed deadlines, and poor performance. Therefore, learning how to prioritise and plan is key to success in both school and life.
