The 11 Plus Maths exam is a key step in many children’s academic journey, assessing a broad range of numerical and reasoning skills. However, even top-performing students often lose marks due to avoidable errors, usually stemming from stress, time mismanagement, or unfamiliarity with question types.
In this comprehensive guide, we highlight the most common 11 plus Maths mistakes and how to prevent them. Plus, learn how tailored support from Mock Exam Centre can help your child stay ahead of the curve.
What is the 11 Plus Maths Exam?
The content of the 11+ Maths paper can vary depending on your region and school, but typically includes:
- Basic arithmetic (addition, subtraction, multiplication, division)
- Word-based problem solving
- Fractions, decimals, and percentages
- Units, measurement, and geometry
- Algebra and numerical patterns
- Data interpretation and statistics
The Top 7 Common Mistakes in 11 Plus Maths and Proven Strategies to Avoid Them
1. Misreading the Question
Overview: Candidates may overlook key terms such as “not”, “estimate”, or “difference”, resulting in incorrect responses.
Suggested Strategy:
- Encourage students to underline or highlight critical terms in each question.
- Foster a habit of careful, deliberate reading.
2. Ineffective Time Management
Overview: Excessive time spent on challenging questions may prevent completion of the exam.
Suggested Strategy:
- Implement the Two-Pass Strategy: attempt all straightforward questions first, then return to the more complex ones.
- Conduct timed practice sessions to simulate real test conditions.
Mock Exam Centre’s timed mock exams provide excellent preparation in this regard. Try a free sample here.
3. Inadequate Word Problem Techniques
Overview: Many students find it difficult to translate verbal descriptions into mathematical operations.
Suggested Strategy:
- Teach active reading techniques such as circling numbers and underlining key operations.
- Deconstruct problems into manageable components.
- Use authentic past paper examples during practice.
4. Over-Reliance on Mental Calculation
Overview: Although showing working is not required for multiple-choice formats, relying entirely on mental arithmetic increases the chance of calculation errors.
Suggested Strategy:
- Encourage rough working out on scrap paper to verify answers.
- Reinforce the habit of double-checking before final selection.
5. Misunderstanding of Units and Measurements
Overview: Students may neglect unit conversions or misunderstand the units required.
Suggested Strategy:
- Regular practice with unit conversion exercises.
- Incorporate a ‘unit verification’ step before finalising each answer.
6. Difficulty with Fractions, Decimals, and Percentages
Overview: These topics often necessitate multi-step reasoning, which can be challenging under time constraints.
Suggested Strategy:
- Practice converting between fractions, decimals, and percentages: e.g., 0.5 = 1/2 = 50%.
- Incorporate visual aids such as pie charts and interactive tools.
7. Errors in Number Transcription or Omitted Steps
Overview: Mistakes can arise from copying numbers incorrectly or skipping crucial steps in mental calculations.
Suggested Strategy:
- Encourage systematic double-checking of work.
- Teach estimation techniques to verify the plausibility of final answers.

Expert Recommendations for 11+ Exam Preparation
Diversify Practice Methods
Incorporate a variety of study formats, including:
- Timed, full-length examination papers
- Focused, topic-specific exercises
- Engaging activities or educational games to alleviate exam-related stress
Develop Examination Stamina
Begin with shorter study sessions and gradually extend their duration. This approach helps children acclimate to maintaining focus for the full length of the exam.
Foster a Growth-Oriented Mindset
Emphasise that errors are valuable learning opportunities. Consistently acknowledge effort, resilience, and progress alongside accuracy.
