Key examiner messages
Top priorities from the principal examiner before you revise
A substantial portion of the marks in Paper 1 was concentrated in Rational Functions and Graphs (15 marks) and Polar Coordinates (15 marks).
In Paper 2, the heaviest weightings lay in Differential Equations (24 marks) and Integration (19 marks).
In Paper 1, Q7 (Polar Coordinates) demanded integration by parts under substitution, which became a prime area for drop-off.
In Paper 2, Q6 and Q7 (Differential Equations) offered 10 marks each for finding particular solutions.

Session analysis
A substantial portion of the marks in Paper 1 was concentrated in Rational Functions and Graphs (15 marks) and Polar Coordinates (15 marks). In Paper 2, the heaviest weightings lay in Differential Equations (24 marks) and Integration (19 marks). In Paper 1, Q7 (Polar Coordinates) demanded integration by parts under substitution, which became a prime area for drop-off. In Paper 2, Q6 and Q7 (Differential Equations) offered 10 marks each for finding particular solutions. Candidates who solidifed their algorithmic techniques for finding integrating factors and auxiliary roots secured high-yielding marks here.

Examiner notes & key calculations
- Neglecting the Pre-requisite step in Integrating Factors: In Paper 2 Q7(b), many candidates failed to divide the equation xdydx−y=x2sinh−1x x \frac{dy}{dx} - y = x^2 \sinh^{-1}x xdxdy−y=x2sinh−1x by x x x before finding the integrating factor, leading to completely incorrect integrals.
- Method of Differences Misalignment: In Paper 1 Q3(b), the fractional term (14)r+1 \left(\frac{1}{4}\right)^{r+1} (41)r+1 caused severe confusion. Many students failed to factor out constant terms correctly, resulting in telescoping series terms that did not cancel correctly.
- Modulus Graph Cusps: In Paper 1 Q6(d), candidates frequently sketched the modulus function y=∣x2+ax+1x+2∣ y = \left|\frac{x^2+ax+1}{x+2}\right| y=∣∣∣∣x+2x2+ax+1∣∣∣∣ with smooth turning points at the x-intercepts instead of sharp cusps, losing key sketching marks.
