01Geometry and Trigonometry
This geometry and trigonometry chapter covers triangle congruence and similarity, circle properties, coordinate geometry, area and volume, and the trigonometric ratios extended to the unit circle. You should be able to prove relationships, apply the sine and cosine laws to non-right triangles, work in radians, and connect trigonometric functions to their graphs and identities.
425 words, about 2 min02Complex numbers
Complex numbers tests arithmetic in the form a + bi, conjugates, modulus and argument, the Argand diagram, modulus–argument form, and the roots of polynomial equations with real coefficients. De Moivre's theorem and geometric interpretations appear in the more demanding questions.
364 words, about 2 min03Statistics and Probability
This statistics and probability chapter explores how data are collected, summarized, and interpreted, and how probability models uncertainty. Expect measures of centre and spread, graphical displays, normal distributions and z-scores, counting-based probability, conditional probability, and critical evaluation of study design and correlation versus causation.
397 words, about 2 min04Discrete Mathematics and Mathematical Reasoning
This domain tests formal reasoning and finite structures: logic and truth values, proof technique, sets, counting, relations, and basic graph and recurrence ideas. Questions reward precision - a correct conclusion with an invalid justification loses marks.
446 words, about 2 min05Sequences and series
Sequences and series examines arithmetic and geometric progressions, sigma notation, sums to infinity and the binomial expansion. You should be able to derive and apply the standard formulae, decide when an infinite sum converges, and extract a specified coefficient from a binomial expansion without expanding everything.
390 words, about 2 min06Linear Algebra and Vector Geometry
Linear algebra and vector geometry practice is about structure: whether a system has solutions, what a matrix does to space, and how lines, planes and vectors sit relative to one another in three dimensions. Reduce the augmented matrix to row echelon form; count pivots in the coefficient block (rank A) and in the augmented block (rank [A b]).
