Distance between two planes
75% of students scored zero — the lowest-performing topic across both Paper 1 datasets.
Affects: Paper 1
!
Image of a point in a plane
Two-thirds of students scored zero; the perpendicular-foot method was rarely attempted correctly.
Affects: Paper 1
!
Second-order differential equations for physical systems
Most students omitted the mass from Newton's second law, producing wrong characteristic equations throughout parts (b) and (c).
Affects: Paper 1
!
Linked de Moivre's theorem parts (multi-part complex number chains)
Parts (d) and (e) of the complex number question saw 75% and 67% of students respectively score zero, unable to link results from earlier parts.
Affects: Paper 1
!
Proof involving matrix transpose and inverse (non-standard matrix proof)
Under 40% gained any mark on the non-standard proof question; students failed to substitute A⁻¹ for B in the given result.
Affects: Paper 2
!
Trigonometric identities used in matrix proofs (geometric series with complex exponentials)
Very few students gained marks on the sum-of-geometric-series proof; students could not express the denominator in terms of sin θ.
Affects: Paper 2
!
Justifying why l'Hôpital's rule is applicable (indeterminate form check)
Many students applied l'Hôpital's rule without first evaluating the limit to confirm it is an indeterminate form (0/0 or ∞/∞).
Affects: Paper 1
!
Coupled differential equations — finding the range after both populations become positive
Only 7% of students scored a mark on part (c); nearly all missed that values of t greater than 5 had to be considered.
