SOF IMO Class 8 2026-27: Dates, Syllabus & Exam Pattern

The SOF International Mathematics Olympiad (IMO) for Class 8 is a school-level mathematics competition conducted by the Science Olympiad Foundation for students in Class 8.

The Olympiad assesses more than routine calculation skills. The Class 8 paper includes Logical Reasoning, Mathematical Reasoning, Everyday Mathematics and an Achievers Section, with questions designed to test mathematical understanding, application and higher-order problem solving.

For the 2026–27 academic session, SOF has announced three Level 1 exam dates:

• 23 October 2026
• 26 November 2026
• 10 December 2026

Each participating school selects one of these dates.

SOF IMO Class 8 2026–27 Overview

SOF states that students from Classes 1 to 12 studying in participating schools can appear for the first level of the International Mathematics Olympiad.

SOF IMO Class 8 Exam Dates 2026–27

The three official Level 1 dates are:

SOF allows each school to select one examination date according to its convenience.

Schools are advised to submit registrations around 30 days before the selected examination date.

What Is SOF IMO?

The SOF International Mathematics Olympiad is an annual mathematics competition designed to assess mathematical ability, logical thinking and application skills.

Unlike a routine school mathematics examination, IMO questions can require students to:

• Recognise mathematical patterns
• Apply concepts in unfamiliar situations
• Interpret figures and diagrams
• Use multi-step reasoning
• Connect different mathematical concepts
• Solve real-life mathematical situations
• Analyse higher-order problems

The competition is conducted internationally through participating schools.

SOF IMO Class 8 Level 1 Exam Pattern

The official Class 8 pattern contains four sections.

SOF uses this pattern for Classes 5 to 10. The paper duration is 1 hour or 60 minutes.

Which Section Has the Highest Number of Questions?

SOF IMO Class 8 Syllabus 2026–27

The official Class 8 syllabus is divided into four sections.

Section 1: Logical Reasoning

SOF describes Section 1 as Verbal and Non-Verbal Reasoning.

Students may encounter reasoning involving:

• Analogy
• Classification
• Series
• Patterns
• Coding relationships
• Direction reasoning
• Ranking
• Logical sequence
• Figure series
• Figure analogy
• Figure classification
• Mirror images
• Visual patterns
• Embedded figures
• Figure completion

The purpose of this section is to test reasoning ability independently of routine mathematics calculations.

Section 2: Mathematical Reasoning

The official Class 8 mathematical syllabus includes:

These topics form the main mathematical core of the examination.

A Square and A Cube

This area can involve understanding square numbers, cube numbers, patterns, properties and relationships involving perfect squares and cubes.

Students should be comfortable recognising:

• Perfect squares
• Perfect cubes
• Square patterns
• Cube patterns
• Numerical relationships
• Applications of squares and cubes

Questions can be more reasoning-oriented than ordinary textbook exercises.

Exponents and Powers

Important ideas can include:

• Exponent notation
• Laws of exponents
• Powers of numbers
• Negative and positive powers
• Scientific-style numerical representation
• Simplifying exponential expressions
• Comparing powers

Olympiad questions may combine exponent laws in multiple steps.

A Story of Numbers

This broad area develops understanding of number systems and number properties.

Questions can involve:

• Integers
• Rational numbers
• Properties of numbers
• Factors
• Multiples
• Divisibility
• Patterns
• Number relationships

Students should understand why mathematical rules work rather than simply memorising them.

Quadrilaterals

This topic covers properties and relationships involving four-sided figures.

Preparation may include:

• Quadrilaterals
• Parallelograms
• Rectangles
• Squares
• Rhombuses
• Trapeziums
• Angle properties
• Diagonals
• Special quadrilateral properties

Number Play

Number Play can involve mathematical patterns, divisibility, special number relationships and numerical reasoning.

Students should practise:

• Digit problems
• Number patterns
• Divisibility
• Factors
• Multiples
• Numerical puzzles
• Logical number relationships

We Distribute, Yet Things Multiply

This area is connected with algebraic multiplication and distributive relationships.

Students may need to work with:

• Distributive property
• Algebraic expressions
• Expansion
• Factor relationships
• Products of expressions
• Mathematical identities

The questions can test both calculation and conceptual understanding.

Proportional Reasoning

Students should understand:

• Ratio
• Proportion
• Direct proportion
• Inverse proportion
• Unitary method
• Percentage relationships
• Scale
• Real-life proportional situations

Proportional reasoning is especially important because questions can be presented as word problems rather than direct equations.

Fractions in Disguise

This topic can connect fractions with:

• Decimals
• Percentages
• Ratios
• Equivalent fractions
• Operations on rational quantities
• Comparisons
• Applications

Students should be able to move comfortably between different representations of the same numerical relationship.

The Baudhayana–Pythagoras Theorem

This topic develops the relationship among the sides of right-angled triangles.

Students should understand:

• Right triangles
• Hypotenuse
• Pythagorean relationship
• Finding missing sides
• Geometrical applications
• Numerical applications

Olympiad questions may combine the theorem with area, geometry or figures.

Exploring Some Geometric Themes

This area can include broader geometrical concepts involving:

• Angles
• Lines
• Polygons
• Geometrical constructions
• Shapes
• Symmetry
• Relationships among figures
• Properties of geometric objects

Students should be comfortable reasoning from diagrams.

Data Handling

Preparation can include:

• Tables
• Bar graphs
• Line graphs
• Pie charts
• Data interpretation
• Mean
• Median
• Mode
• Basic probability
• Comparison of datasets

Questions may require students to extract information from charts rather than perform isolated calculations.

Algebra Play

This topic develops algebraic reasoning.

Students may need to work with:

• Variables
• Constants
• Algebraic expressions
• Simplification
• Linear relationships
• Equations
• Identities
• Patterns
• Substitution

The emphasis can extend beyond routine solving to recognising structure and mathematical relationships.

Area

Area questions can involve:

• Squares
• Rectangles
• Triangles
• Parallelograms
• Trapeziums
• Composite figures
• Application problems
• Relationships between perimeter and area

Section 3: Everyday Mathematics

SOF states that Section 3 follows the same syllabus as Section 2. The difference lies mainly in the way questions are framed.

Everyday Mathematics applies mathematical concepts to practical situations such as:

• Money
• Measurement
• Distances
• Rates
• Percentages
• Shopping calculations
• Data
• Areas
• Ratios
• Time
• Real-world comparisons

Students should therefore practise translating a real-world situation into a mathematical model.

Section 4: Achievers Section

The Achievers Section consists of Higher Order Thinking questions based on the Section 2 Mathematics syllabus.

Achievers questions may require:

• Multi-step calculation
• Combining several concepts
• Pattern discovery
• Advanced logical application
• Diagram analysis
• Identifying hidden conditions
• Comparing multiple methods
• Applying mathematical concepts in unfamiliar settings

Is the Achievers Section a Separate Syllabus?

Students therefore do not need an entirely separate set of chapters. They need deeper practice on the existing Class 8 topics.

Class 7 Syllabus Is Also Included

An important feature of Level 1 is that the paper is not entirely based on Class 8.

Why Class 7 Mathematics Should Be Revised

Class 7 concepts provide much of the foundation for Class 8 mathematics.

Possible relevant areas can include:

• Integers
• Fractions
• Decimals
• Rational numbers
• Ratio and proportion
• Percentage
• Simple equations
• Geometry
• Mensuration
• Data handling
• Algebraic expressions

SOF IMO Class 8 Level 2

SOF IMO has a second level for qualifying Class 8 students.

SOF confirms that Level 2 is conducted for students from Classes 3 to 12.

For the 2026–27 session, the exact Level 2 date is expected to be announced by December 2026.

SOF IMO Class 8 Level 2 Exam Pattern

For Classes 5 to 10, the official Level 2 pattern is:

Level 2 therefore contains 50 questions for 60 marks.

Unlike Level 1, there are no separate Logical Reasoning and Everyday Mathematics sections in the Level 2 pattern.

Level 1 vs Level 2

SOF specifically states that Level 2 questions are based only on the current class syllabus.

Who Qualifies for SOF IMO Level 2?

A Class 8 student can qualify through any one of three routes:

This allows strong performers to qualify through international, zonal or school-level criteria.

SOF IMO Class 8 Eligibility

Students studying in Class 8 in participating schools can appear for the Level 1 examination.

SOF does not prescribe a previous-school-exam percentage or previous Olympiad rank as a condition for Level 1.

Students from Classes 1 to 12 are eligible for the first-level IMO through their participating schools.

SOF IMO Registration

Students register through their schools.

The participating school submits the registration details and conducts the Level 1 examination during school hours.

SOF IMO Registration Fee

For students in India, Bhutan and Nepal, the standard registration fee is:

Schools may additionally charge up to ₹30 per student for specified examination-related expenses such as coordination and teacher remuneration.

Students with major physical disabilities and eligible Indian students whose parents were martyred during defence operations are exempt from the registration fee under SOF rules.

Is SOF IMO Online or Offline?

The test is objective and uses multiple-choice questions.

What Is the Medium of the Exam?

SOF states that the examination medium is English.

Students should therefore be comfortable interpreting mathematical terminology and word problems in English.

Which Boards Does SOF IMO Follow?

SOF states that the question papers are set with reference to:

• CBSE
• ICSE/ISC
• State Board syllabi

The Olympiad is therefore not restricted to students from one school board.

Does SOF IMO Have Negative Marking?

Students should nevertheless prioritise accuracy because rank depends directly on the number of marks scored.

How Are Ties Resolved?

SOF normally gives the higher rank to the student with the higher total score.

When two or more students obtain the same total marks, section-wise priority is used to determine rank.

For Classes 5 to 10, the published priority order is:

1. Achievers Section
2. Mathematical Reasoning
3. Everyday Mathematics
4. Logical Reasoning

SOF IMO Class 8 Awards 2026–27

For two-level Olympiads such as IMO, final International and Zonal awards for Classes 3 to 12 are based on Level 2 performance.

For 2026–27, the top five International rankers receive:

The top three International rank holders also receive Gold, Silver and Bronze International Medals respectively, along with a Certificate of Outstanding Performance.

SOF also provides zonal awards, medals, certificates and school-level recognition according to its published award structure.

SOF IMO Level 1 Recognition

All participating students receive:

• Certificate of Participation
• Student Progress Report

SOF also awards Level 1 distinctions based on zonal and school performance.

The Student Progress Report provides performance analysis across different comparison levels.

What Happens If Level 2 Is Not Conducted?

Under the current 2026–27 schedule, however, Level 2 is planned for Classes 3 to 12.
