IB Diploma Programme Mathematics: Analysis and Approaches

Component-based qualification

Source: official International Baccalaureate specification, verified 2026-09-04. Both tiers modeled in full. Weighting and duration are read directly from the official public subject brief (first assessments 2021). Paper 1 and Paper 2 Higher Level mark totals (110 marks each, 2 hours each) are read directly from the official freely public specimen papers, directly fetched and read this session; the same document could not be fully extracted through available tooling far enough to confirm the Standard Level papers or Paper 3. Standard Level Paper 1/Paper 2 (80 marks each), Higher Level Paper 3 (55 marks, two compulsory extended-response problem-solving questions, 1 hour, technology required) and the Mathematical Exploration (20 marks at both tiers, marked against five criteria -- Presentation (4), Mathematical Communication (4), Personal Engagement (3), Reflection (3), Use of Mathematics (6) -- an internally assessed written investigation, compulsory at both tiers) were independently corroborated against a current, actively maintained third-party IB revision resource that publishes exact maximum-mark grade-boundary tables; those tables agree exactly with the primary specimen document everywhere the two overlap (Higher Level Paper 1 and Paper 2).
