Every IB Maths exam season in Hong Kong, capable students lose marks not because they don’t understand the content — but because of avoidable exam mistakes. These errors are rarely about intelligence; they come from pressure, poor technique, and lack of exam awareness.
At Mathzem, we analyse exam scripts and patterns year after year. This guide breaks down the most common IB Maths exam mistakes Hong Kong students make, and explains exactly how to avoid them.

Why Small Mistakes Matter So Much in IB Maths
IB Maths marking is:
- Method-focused
- Step-sensitive
- Strict about communication
Small errors:
- Add up quickly
- Reduce grade boundaries margin
- Turn strong answers into partial credit
Avoiding mistakes can increase scores without learning new content.
Mistake 1: Misreading the Question
Under exam pressure, students often:
- Skip key words
- Ignore conditions
- Answer the wrong part
How to avoid it:
- Read the question twice
- Underline command terms
- Identify exactly what is being asked
Mistake 2: Poor Use of Calculator
Common calculator-related errors include:
- Incorrect modes
- Rounding too early
- Blindly trusting outputs
How to avoid it:
- Check calculator settings before the exam
- Round only at the final step
- Sanity-check answers
Technology helps, but only when used intelligently.
Mistake 3: Skipping Logical Steps
Many students:
- Jump straight to the answer
- Omit working
- Lose method marks
How to avoid it:
- Show all reasoning clearly
- Write equations even if using a calculator
- Structure solutions logically
Clear working earns marks even if the final answer is wrong.
Mistake 4: Weak Mathematical Communication
IB Maths rewards clarity.
Common issues:
- Unlabelled graphs
- Undefined variables
- Disorganised solutions
How to avoid it:
- Define variables
- Label axes and diagrams
- Present work neatly
Presentation matters more than students expect.
Mistake 5: Running Out of Time
Time pressure causes:
- Rushed thinking
- Incomplete answers
- Panic
How to avoid it:
- Practise under timed conditions
- Learn when to move on
- Allocate time proportionally to marks
Good pacing protects accuracy.
Mistake 6: Ignoring Command Terms
Words like:
- Show
- Explain
- Justify
Require reasoning, not just calculations.
How to avoid it:
- Memorise command term expectations
- Always explain when asked
- Connect steps logically
Mistake 7: Exam Stress Taking Over
Stress leads to:
- Simple arithmetic errors
- Poor decisions
- Mental blocks
How to avoid it:
- Practise under exam conditions
- Use calm breathing techniques
- Stick to familiar methods
Confidence comes from preparation.
