    • Three-dimensional geometry: angle between a line and a plane in triangular right prisms
    • Approximations and percentage errors: absolute errors in total surface area of cones
    • Binomial expansion up to four terms and numerical estimations
    • Navigation and celestial geometry: distance along parallels of latitude and speed in knots
    • Trigonometry: applying cosine rule in obtuse triangles
    • Variations: partial variations involving square relationships
    • Loci: shading regions satisfying multi-variable distance and angle bisector constraints
    • Commercial arithmetic: hire purchase, down payments, and compound interest rates per month
    • Mixtures and proportions: weighted average cost and selling price for targeted profits
    • Trigonometric wave equations: determining amplitude, period, and phase angle
    • Analytical geometry: determining center, radius, and constant values in circle equations
  • Section II (Questions 17 – 24):
    • Statistics: ogive curves, cumulative frequency, median, quartile deviation, percentiles, and grouped data mean
    • Financial mathematics: progressive income tax bands, PAYE calculations, personal reliefs, basic and net salary
    • Geometric transformations: plotting shear transformations, invariant lines, and shear transformation matrices
