Preparing for IGCSE examinations is not simply about studying more. It is about studying with a clear strategy.
Mathematics and Science require students to understand concepts, apply knowledge, interpret questions and solve problems under examination conditions. Simply reading notes repeatedly or memorising answers may not be enough.
A good preparation strategy should combine understanding, practice, revision and exam technique.
Here is a practical approach students can use.
1. Start by Understanding What You Need to Learn
Before beginning intensive revision, students should understand the requirements of their particular IGCSE subjects.
Create a list of the major topics covered in the syllabus and identify:
- Topics you understand well
- Topics you understand partially
- Topics you find difficult
- Topics you have not studied sufficiently
This gives you a clearer picture of where your time should go.
Do not spend most of your revision time studying topics you already know simply because they feel comfortable.
2. Identify Your Learning Gaps
One of the most important steps in exam preparation is identifying what you do not understand.
A student may feel comfortable with a topic after reading through their notes but discover a problem when attempting questions.
Try solving questions without looking at the solution.
If you repeatedly struggle with a particular type of question, go back to the underlying concept before attempting more questions.
This approach is much more productive than repeatedly practising something you already know.
3. Understand Concepts Before Memorising Them
Mathematics and Science contain information that students need to remember, but understanding should come first.
For example, memorising a Physics formula is useful. Understanding what the quantities represent and when the formula should be applied is even more important.
The same applies to Chemistry and Biology.
Ask yourself:
What does this mean?
Why does it happen?
How are these ideas connected?
How would I apply this to a different question?
These questions encourage deeper learning and make it easier to deal with unfamiliar problems.
4. Practise With Exam-Style Questions
Once you understand a topic, practise applying it.
Start with straightforward questions and gradually move towards more challenging problems.
As you progress, introduce questions that require you to:
- Apply multiple concepts
- Interpret information
- Explain your reasoning
- Work through several steps
- Apply knowledge in unfamiliar situations
This helps bridge the gap between understanding a topic and using that understanding in an examination.
5. Learn From Your Mistakes
Getting a question wrong is not the end of the learning process.
The important question is:
Why did I get it wrong?
Was it because you:
- Misunderstood the question?
- Forgot an important concept?
- Used the wrong formula?
- Made a calculation error?
- Missed a step?
- Misinterpreted the information?
Keep a simple record of recurring mistakes.
Over time, this can reveal patterns in your learning and show you exactly where additional practice is needed.
6. Do Not Leave Past Papers Until the Last Minute
Past papers are valuable because they allow students to practise applying their knowledge in an examination-style environment.
However, they should not replace learning.
A useful progression is:
Learn → Practise → Review → Apply → Test
Begin with individual topics and gradually move towards complete papers.
As the examination approaches, practise working through papers within the appropriate time constraints.
7. Develop a Revision Schedule You Can Actually Follow
A complicated revision timetable is not necessarily an effective one.
Create a realistic schedule that gives you regular opportunities to study each subject.
For example:
Monday: Mathematics
Tuesday: Chemistry
Wednesday: Physics
Thursday: Mathematics
Friday: Biology
Weekend: Mixed revision and practice questions
The exact schedule will depend on your subjects, workload and examination dates.
Consistency matters more than creating an impressive timetable that becomes impossible to maintain.
8. Practise Explaining What You Have Learned
One useful test of understanding is being able to explain a concept without relying on your notes.
Choose a topic and explain it as if you were teaching it to someone else.
If you cannot explain the idea clearly, you may need to revisit it.
This technique can reveal gaps that are not always obvious when simply reading through revision materials.
9. Ask for Help When You Are Stuck
There is no advantage in spending weeks struggling with the same concept when appropriate support is available.
If you repeatedly find a topic difficult, ask your teacher, tutor or another trusted academic resource for help.
The earlier a learning gap is identified, the more time there is to address it before the examination.
One-to-one tutoring can be particularly useful when a student needs more time to explore a concept, ask questions or work through problems at their own pace.
10. Build Confidence Through Preparation
Exam confidence does not mean believing that every question will be easy.
It comes from knowing that you have prepared properly and have strategies for dealing with difficult questions.
A well-prepared student can encounter an unfamiliar problem and think:
"I may not know the answer immediately, but I know how to approach it."
That mindset becomes increasingly valuable as examination questions become more demanding.
A Better Way to Prepare for IGCSE
Effective IGCSE preparation is not about spending every available hour studying.
It is about making each study session purposeful.
Focus on:
Understanding concepts.
Identifying learning gaps.
Practising application.
Learning from mistakes.
Working through exam-style questions.
Building confidence through consistent preparation.
For Mathematics and Science especially, students need to move beyond memorising information and develop the ability to think, reason and apply what they know.
At Onayemi Academy, lessons are structured around each student's current ability, learning needs and academic goals, with clear explanations, guided practice and progressively challenging questions.
