Algebra
Inequalities, identities, polynomials, functional relationships and structural manipulation.
Olympiad mathematics rewards depth, originality, proof and persistence. Training should therefore be systematic, long-term and much broader than learning isolated tricks.
Inequalities, identities, polynomials, functional relationships and structural manipulation.
Euclidean geometry, transformations, configurations, ratios, circles and proof.
Divisibility, congruences, Diophantine equations and arithmetic structure.
Counting, invariants, graph ideas, extremal reasoning and constructive arguments.
Learn ideas deeply, attempt hard problems, analyse failed approaches, and write solutions another mathematician can follow.
