    Common Exam Mistakes

    Pitfalls to avoid in your exams

    • •Confusing position vectors with displacement vectors, frequently calculating a - b instead of b - a
    • •Failing to use appropriate vector notation (underlines or arrows) in handwriting, leading to confusion between scalar and vector variables
    • •Incorrectly assuming vectors are parallel without explicitly showing one is a scalar multiple of the other
    • •Neglecting to square root the sum of squares when calculating magnitude, or treating the magnitude as a vector quantity
    • •Dividing an equation by a trigonometric function (e.g., dividing by cos x) instead of factorizing, causing the loss of a valid set of solutions
    • •Using degree mode calculators for questions involving calculus or small angle approximations, where radians are mandatory
    • •Incorrectly assuming sin(A+B) = sinA + sinB, failing to apply the correct compound angle expansion
    • •Omitting the constant of integration or misapplying signs when integrating trigonometric functions

    Top Examiner Tips

    Expert advice for exam success

    • •Use column vector notation for intermediate calculations to reduce algebraic errors, but convert back to i, j, k form if the question demands it
    • •In geometric proofs, you must explicitly state 'vectors are parallel and share a common point' to secure the final reasoning mark for collinearity
    • •When finding the angle between vectors, ensure you calculate the angle between the 'tails' of both vectors using the cosine rule or dot product (if Further Math)
    • •For mechanics questions, remember that speed is the magnitude of the velocity vector; do not leave your answer as a vector if asked for speed
    • •In 'Show that' questions, manipulate only one side of the identity (usually the LHS) to match the other; never move terms across the equals sign as this assumes the result
    • •Always check the domain of the question immediately; if the range is given in terms of π, your answers must be in radians and exact forms
    • •When solving equations involving k*x (e.g., sin 2x), adjust the interval first (e.g., 0 ≤ 2x ≤ 720) to ensure you capture all solutions before dividing back
    • •Draw a Venn diagram immediately for any question involving 'given that' or overlapping sets to visualize the reduced sample space
