Top 5 Mistakes in IGCSE Exams — And How to Avoid Them
As the May/June 2025 IGCSE exam session approaches, students are entering the final phase of preparation.
However, many candidates — even well-prepared ones — lose valuable marks because of preventable mistakes. These errors are often not about knowledge gaps, but about exam strategy, time management, and attention to detail.
Understanding the most common mistakes — and training to avoid them — can make the difference between a B and an A*.
Here are the top 5 mistakes students make in IGCSE exams — and how you can avoid them.
1. Misreading the Question
One of the most common (and costly) mistakes is rushing into an answer without fully understanding what the question requires.
Students often:
- Miss command words like "explain" versus "describe"
- Ignore critical details like units, conditions, or constraints
- Answer only part of a multi-part question
How to avoid it:
- Take 10–15 seconds to carefully read every question twice.
- Underline or circle key command terms and conditions.
- Plan your structure before starting long answers.
In Maths and Sciences, misreading a simple instruction can cause a cascade of wrong answers through an entire question set.
2. Poor Time Management
Many students spend too much time on early questions and rush the later sections — losing marks even on topics they know well.
Common timing errors include:
- Spending too long perfecting easy questions
- Getting stuck on a hard problem without moving on
- Not leaving time to check answers
How to avoid it:
- Practice full timed past papers under real exam conditions.
- Train yourself to move on after 2–3 minutes if stuck.
- Reserve the final 10 minutes of the exam for reviewing key answers.
IGCSE exams are designed not only to test knowledge but also time pressure management.
3. Leaving Out Working or Justifications
Especially in Maths and Science exams, method marks are critical.
Students often:
- Skip working steps
- Leave out units
- Fail to show how answers were derived
Even if your final answer is wrong, partial method marks can save your grade — but only if you show clear, logical working.
How to avoid it:
- Always show step-by-step calculations.
- Label each working stage clearly.
- Double-check that all units are stated where necessary.
4. Ignoring Real-World Application and Context
In subjects like Business Studies, Geography, and Sciences, examiners often look for real-world application, not just textbook knowledge.
Students lose marks by:
- Giving generic, theoretical answers without applying them to a given case study
- Failing to link answers to the context provided in the question
How to avoid it:
- Practice applying concepts to real-world examples during revision.
- In the exam, always refer back to the scenario or case in your answer.
Contextual application often separates A/A* students from the rest.
5. Lack of Practice with Predictive, Syllabus-Aligned Questions
Students often focus on random revision or outdated past papers, missing the real demands of the current syllabus.
This leads to:
- Wasted time on low-probability topics
- Missing the skills examiners are emphasizing now
- Underestimating new question styles introduced after syllabus updates
How to avoid it:
- Focus revision on syllabus-prioritized topics.
- Train with predictive practice papers based on real trend analysis.
- Simulate real exam conditions regularly.
