Registration: Your school picks one of the three dates above, and registrations must reach SOF 30 days before that chosen date — so 23 September 2026 for the October date, 27 October for the November date, and 10 November for the December date. Two things parents miss: the school chooses the date, not the family, and once the school has chosen, the date cannot be changed. Ask your school coordinator which date they have picked, and work backwards from the cutoff for that date only.
The deadline is set by your school, not by you
Most parents find the exam date and assume they have until then. The registration window closes long before it, and for some papers it has already started closing. Here is how it actually works.
- Your school registers your child and your school picks which of the 2–3 dates the class sits. The family does not choose.
- For SOF papers, registrations must reach SOF exactly 30 days before that chosen date — and once the school has chosen, the date cannot be changed.
- CREST is the exception: it registers students directly, online, with no school involved. It is the one body a parent can act on alone.

Exam pattern
How the IMO paper is structured
| Section | Questions | Marks per question | Section total |
|---|---|---|---|
| Logical Reasoning | 15 | 1 | 15 |
| Mathematical Reasoning | 20 | 1 | 20 |
| Everyday Mathematics | 10 | 1 | 10 |
| Achievers Section | 5 | 3 | 15 |
| Total | 50 questions | — | 60 marks · 60 minutes |
SOF states the split directly: 60% of Level 1 questions come from the current class syllabus and 40% from the previous class — so a Class 7 IMO paper is 60% Class 7 and 40% Class 6. The Achievers Section is the exception; those five questions are drawn from Class 7 material only.

Two things to know about this list. First, the Logical Reasoning section (15 questions) is a separate spine — verbal and non-verbal reasoning, analogies, series, coding-decoding — and is not drawn from the chapters above. Second, SOF still publishes its Class 7 topic list using the older NCERT chapter names (Factors and Multiples, Decimals, Integers, Simple Equations, Lines and Angles, Triangles, Congruence of Triangles, Data Handling, Constructions and Tilings) — those are the same topics as the Ganita Prakash chapters above, just under their old labels. Chapters 11 and 12 (ratio and percentage, rational numbers) are not named separately in SOF's published list but sit inside the same Class 7 book, and other bodies' Class 7 maths papers do test them. Our curator taxonomy also flags four topics as olympiad-scope even though the 2026-27 NCERT spine has moved or dropped them: exponents and powers, scientific notation, 3-D shapes (nets and views), and the Grade 7 perimeter-and-area extensions for parallelograms and circles.
