Logical Reasoning
- Patterns: Spot the rule in a row of shapes or numbers and pick what comes next.
- Odd One Out: Find the one picture or item that does not belong with the rest.
- Measuring Units: Compare objects by size, length or weight using simple units.
- Geometrical Shapes: Recognise and count shapes like circles, triangles and squares inside pictures.
- Spatial Understanding: Understand positions such as above, below, inside, near and far.
- Grouping of Figures: Sort figures into groups that share a common feature.
- Analogy: Find the pair that is related in the same way as a given pair.
- Ranking Test: Work out positions in a line or order, such as third from the left.
- Problems based on Figures: Reasoning questions answered by looking closely at pictures and figures.
Mathematical Reasoning
- Numerals: Reading and writing numbers using digits.
- Number Names: Writing numbers in words and matching number words to digits.
- Number Sense (2-digit numbers): Place value, comparing and ordering numbers up to 99.
- Addition: Putting small numbers together, including simple word problems.
- Subtraction: Taking away and finding the difference between small numbers.
- Lengths, Weights and Comparisons: Comparing things as longer or shorter, heavier or lighter.
- Time: Early ideas of time such as days of the week and simple clock reading.
- Money: Recognising coins and notes and adding small amounts.
- Geometrical Shapes and Solids: Naming flat shapes and everyday solids like balls, boxes and cones.
Everyday Mathematics
- Maths in daily life: Real-life word problems using this class's Mathematical Reasoning topics.
Achievers Section

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.
