IMO Class 12 syllabus 2026-27

Logical Reasoning

  • Verbal Reasoning: Reasoning with words, letters and numbers, for example series, codes and analogies.
  • Non-Verbal Reasoning: Reasoning with pictures and figures, for example patterns, mirror images and hidden shapes.

Mathematical Reasoning (Mathematics)

  • Relations and Functions: Types of relations and functions, including one-one and onto.
  • Inverse Trigonometric Functions: Inverses of sine, cosine and tangent and their properties.
  • Matrices: Arrays of numbers and the operations on them.
  • Determinants: Values linked to square matrices, used to solve equations.
  • Continuity and Differentiability: When a function is smooth and how to differentiate it.
  • Application of Derivatives: Using derivatives for rates of change, maxima and minima.
  • Integrals: Integration as reverse differentiation and methods to integrate.
  • Application of Integrals: Finding areas under curves using integration.
  • Differential Equations: Equations involving derivatives and how to solve simple ones.
  • Vector Algebra: Quantities with size and direction, and vector products.
  • Three Dimensional Geometry: Lines and angles in 3-D space.
  • Linear Programming: Finding the best value of a quantity under given limits.
  • Probability: Conditional probability, Bayes' theorem and distributions.

Mathematical Reasoning (Applied Mathematics option)

  • Numbers, Quantification and Numerical Applications: Practical number work such as modular arithmetic and mixtures.
  • Solutions of Simultaneous Linear Equations: Solving several equations together, including by matrices.
  • Matrices: Matrix operations used in applied problems.
  • Determinants: Determinant values and their uses.
  • Application of Derivatives: Rates of change and optimisation in business and economics.
  • Integration: Methods of integration.
  • Application of Integrations: Using integration for areas and applied totals.
  • Differential Equations: Forming and solving simple differential equations.
  • Probability: Probability and distributions for real decisions.
  • Inferential Statistics: Drawing conclusions about a population from sample data.
  • Index Numbers: Measuring changes in prices or quantities over time.
  • Time-Based Data: Analysing data collected over time to spot trends.
  • Financial Mathematics: Loans, annuities, investments and depreciation.
  • Linear Programming: Optimising a result under constraints.

Everyday Mathematics

  • Maths in daily life: Quantitative aptitude: number, percentage and data problems set in everyday situations.

Achievers Section

  • Matrices and Determinants: Challenging matrix and determinant problems.
  • Application of Derivatives: Harder rate-of-change and maxima/minima questions.

  • Differential Equations: Tougher differential equation questions.
  • Linear Programming: Demanding optimisation problems.
  • Probability: Multi-step probability problems.

About the IMO exam

How the exam works

Mode: Offline, objective multiple-choice paper held in school during school hours; each exam date has its own paper. · Levels: Level 1: Classes 1-12, held in the student's own school. Level 2: Classes 3-12 only; qualifiers are the class-wise top 5% internationally, the top 25 per zone per class, and school class toppers (where at least 10 students of that class sat the exam and the topper scored at least 50%). Level 1 questions are about 60% from the current class syllabus and 40% from the previous class; the Achievers Section and all of Level 2 use the current class syllabus only. · Duration: 60 minutes · Questions: Level 1: Classes 1-4 have 35 questions (Logical Reasoning 10, Mathematical Reasoning 10, Everyday Mathematics 10, Achievers 5). Classes 5-12 have 50 questions (Logical Reasoning 15, Mathematical Reasoning 20, Everyday Mathematics 10, Achievers 5); for Classes 11-12 the Mathematical Reasoning section has a Mathematics or an Applied Mathematics syllabus. Level 2: Classes 3-4 have 30 Mathematics + 5 Achievers; Classes 5-10 have 45 Mathematics + 5 Achievers; Classes 11-12 have 25 Mathematics + 20 Mathematical Reasoning/Applied Mathematics + 5 Achievers. · Marking: 1 mark per question except the Achievers Section: 2 marks each for Classes 1-4 (40 marks in total) and 3 marks each for Classes 5-12 (60 marks in total). SOF's published pattern does not mention negative marking. Ties are broken by section priority: Achievers first, then Mathematical Reasoning, Everyday Mathematics, Logical Reasoning. · Language: English only

How to register

Only through the child's school: the school registers with SOF and sends the student forms, usually at least 30 days before its chosen exam date. Individual registrations are not accepted. Fee: Rs 170 per student per Olympiad incl. GST (India, Bhutan, Nepal), and schools may collect up to Rs 30 extra; US$11 elsewhere.

When it happens

Next Level 1 school dates: 26 November and 10 December 2026. Earlier dates (23 October 2026) have passed. Each school chooses one date; a future exam date does not mean registration is still open. SOF asks schools to submit registrations at least 30 days before their selected date. Level 2 is for qualifying Classes 3–12 only; SOF plans to announce the exact date by December 2026 and provisionally indicates the second or third Sunday of February 2027. This is tentative, not a confirmed exam date. Results are normally available within about 8 weeks. Status checked 1 November 2026; times are IST.

Previous-year paper collection for Class 12

SOF lists a five-year IMO Level 1 eBook for this class. Purchase and a publisher account are required to download. This link opens the official collection; it is not a question-paper attachment.
