IMO Class 9 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
- Number Systems: Rational and irrational numbers, real numbers and their decimal forms.
- Polynomials: Terms, degree, zeroes and factorising polynomials.
- Algebraic Identities: Standard identities used to expand and factorise expressions quickly.
- Coordinate Geometry: Plotting and locating points on the x-y plane.
- Linear Equations in Two Variables: Equations like ax + by = c and their graphs.
- Introduction to Euclid's Geometry: The basic definitions, axioms and postulates geometry is built on.
- Lines and Angles: Angle rules for intersecting and parallel lines.
- Sequences and Progressions: Number sequences that follow a rule, including arithmetic progressions.
- Triangles: Congruence rules and properties of triangles.
- Quadrilaterals: Properties of parallelograms and other four-sided figures.
- Areas of Parallelograms and Triangles: Comparing areas of figures on the same base and between parallels.
- Circles: Chords, arcs and angle properties of circles.
- Area and Perimeter: Finding areas and perimeters of triangles, quadrilaterals and other flat figures.
- Constructions: Drawing angles, bisectors and triangles with ruler and compass.
- Surface Areas and Volumes: Outer area and capacity of cubes, cylinders, cones and spheres.
- Statistics: Organising data and finding mean, median and mode.
- Introduction to Probability: Chance of an event, measured from experiments and outcomes.
Everyday Mathematics
- Maths in daily life: Real-life problems based on Mathematical Reasoning topics plus general quantitative aptitude.
Achievers Section
- Higher Order Thinking questions: Harder, multi-step questions on this class's Mathematical Reasoning topics; worth more marks each.
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.
