The four IMO sections, decoded: what each one really asks of your child

Every SOF IMO paper for junior classes is built from the same four sections. Once you understand what each section is really probing, your child’s scorecard stops being a single mysterious number and becomes a map: it tells you where practice will pay off. Question counts and marks per section can vary by class and year, so treat the current official SOF notification as the final word on specifics — the character of each section, though, is stable.

Section 1: Logical Reasoning

This section barely touches the school syllabus at all. It asks about patterns and series, ranking and ordering, mirror images, directions, and figure puzzles. Children rarely see this material in class, which is exactly why a little targeted exposure goes a long way — the first time a child meets a coding–decoding question should not be exam day. The upside: these questions become genuinely fun once familiar, and many children end up naming this their favourite section.

Section 2: Mathematical Reasoning

The heart of the paper, and usually its largest section. This is the class-level syllabus — number sense, operations, fractions, geometry — applied with a twist: a question phrased in reverse, an extra step hidden in the wording, or options built from the most common mistakes. Depth in the syllabus topics is what wins here; there is no shortcut around actually understanding the math.

Section 3: Everyday Mathematics

The same syllabus again, but wrapped in daily life: money, time, measurement, shopping, travel. The math is rarely harder than in Section 2 — the challenge is translation. A child must read a small story, decide which operation the situation calls for, and ignore the numbers that do not matter. Reading word problems slowly and stating “what is this asking?” before calculating is the single highest-value habit for this section.

Section 4: Achievers — small, heavy, decisive

The Achievers Section is short — only a handful of questions — but each one carries higher marks than a regular question and is deliberately harder: multi-step, multi-statement, or one small conceptual level above the class. Because so many children score similarly on the first three sections, a couple of Achievers questions frequently separate adjacent ranks. This is where composure earns its keep.

How to use this as a parent

• ★A low Logical Reasoning score usually means unfamiliarity, not weakness — a few weeks of pattern puzzles fixes it fast.
• ★A low Mathematical Reasoning score points to a syllabus topic that needs rebuilding; find which one before adding more practice.
• ★A low Everyday Mathematics score with a healthy Section 2 is a reading issue — practise the translation step, not more arithmetic.
• ★Achievers improves last: it rides on the other three plus calm. Full timed mocks are its best preparation.

LittleMathematicians mocks follow this exact four-section structure and marks scheme, timed server-side like the real thing, and the scorecard afterwards breaks results down section by section and topic by topic — so you can act on the map rather than guess. It is free during early access.
