    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.
    • Incorrectly expanding brackets, e.g., forgetting to multiply the second term inside the brackets.
    • Making sign errors when solving equations, e.g., moving terms across the equals sign without changing the sign.
    • Confusing the direction of the inequality sign when multiplying or dividing by a negative number.
    • Substituting values into expressions without following the correct order of operations.
    • Finding the nth term of a sequence incorrectly by not checking the difference between terms.
    • Misapplying the order of operations, leading to incorrect arithmetic results.
    • Confusing the laws of indices, e.g., multiplying when should add exponents.

    Top Examiner Tips

    Expert advice for exam success

    • Always show your working clearly; marks are often awarded for method even if the final answer is wrong.
    • Check your answers by substituting them back into the original equation or expression.
    • When solving inequalities, remember to reverse the inequality sign when multiplying or dividing by a negative number.
    • For graphs, label axes and plot points accurately; use a ruler for straight lines.
    • Practice mental arithmetic to improve speed and accuracy in non-calculator sections.
    • Read questions carefully to identify whether an answer requires a decimal, fraction, or percentage.
    • Show all working steps clearly to gain method marks even if the final answer is wrong.
    • Check your answers by substituting back into the original equation.
