Common Exam Mistakes
Pitfalls to avoid in your exams
- •Misapplying the order of operations, e.g., calculating 2 + 3 × 4 as 20 instead of 14.
- •Confusing the rules for multiplying and dividing fractions, e.g., not flipping the second fraction when dividing.
- •Incorrectly converting between fractions, decimals, and percentages, e.g., writing 0.5 as 5% instead of 50%.
- •Mixing up ratio and proportion concepts, e.g., dividing a quantity incorrectly when sharing in a ratio.
- •Errors in expanding brackets, e.g., forgetting to multiply the second term inside the brackets.
- •When solving equations, performing the same operation on only one side of the equation.
- •Misapplying index laws, e.g., adding indices when multiplying powers with the same base incorrectly.
- •Not converting to standard form correctly, e.g., placing the decimal point in the wrong position.
Top Examiner Tips
Expert advice for exam success
- •Always show your working clearly; even if the final answer is wrong, you may gain method marks.
- •Check your answers by substituting back into the original equation or problem.
- •Practice mental arithmetic to save time on simple calculations.
- •Read word problems carefully to identify the key information and what is being asked.
- •Use a calculator for complex calculations, but be aware of the order of operations.
- •Revise the laws of indices and standard form thoroughly as they often appear in exam questions.
- •When working with fractions, ensure you have a common denominator before adding or subtracting.
- •In ratio problems, always find the value of one part first before calculating the total.
Qualification Units
How this qualification is graded
Vocational qualifications are marked against criteria, not an exam percentage. Each unit is assessed across three bands - build up from Pass by applying your knowledge to realistic workplace scenarios.
Accurately describe and explain the core knowledge for the unit and link it to the given scenario.
Apply and analyse that knowledge in detail, showing why it matters in the workplace context.
Evaluate and justify decisions, weigh up alternatives and make well-reasoned professional recommendations.
