IMO Maths Olympiad Class 4 (2026-27): Complete Syllabus, Exam Pattern & Free Preparation Guide

If you’ve got a Class 4 kid at home who actually enjoys number problems (lucky you!), the IMO Maths Olympiad Class 4 is worth putting on your radar. It’s run by the Science Olympiad Foundation, and honestly, it’s one of the better ways for a nine or ten-year-old to test how they think under a bit of pressure, not just what they’ve memorised. I’ve worked with a fair number of students preparing for this exam, and most parents come to me with the same set of questions: when is it, what’s actually in it, and how much prep does a Class 4 child really need? Let’s get into all of that.

So What Exactly Is the IMO Maths Olympiad for Class 4?

IMO stands for International Mathematics Olympiad, and it’s basically SOF’s flagship maths competition for school students, open right from Class 1 up to Class 12. What makes it interesting for younger kids is that it’s not testing anything outside their comfort zone — the questions still come from the Class 4 syllabus, just asked in a way that makes children think a little harder than a regular school test would.

Here’s something that puts a lot of parents at ease: the syllabus is aligned with NEP 2020, NCF 2022, NCERT, and CBSE, and it also accounts for various state boards. So there’s no separate “Olympiad textbook” your child absolutely needs. If they’re solid on their regular Class 4 maths, they’ve already got most of the foundation they need for this maths olympiad for class 4.

When Is the Class 4 IMO Exam in 2026-27?

For this academic year, SOF has scheduled the exam across three possible dates: 23 October, 26 November, and 10 December 2026. Schools pick just one of these for their students, so which date applies to your child depends entirely on what their school decides. It’s worth checking with the school directly rather than assuming, since I’ve seen a fair bit of confusion around this every year.

Who Can Actually Sit for It?

There are two stages to know about:

Level 1 is open to everyone from Class 1 through Class 12, and it happens right there in school during regular hours.
Level 2 is a different story; it’s only for Classes 3 to 12, and only students who clear the cut-off in Level 1 get invited.

So a Class 4 child can, in theory, sit for both rounds but Level 2 only comes into play if they do well enough in Level 1 first.

The Exam Pattern (This Is the Part Everyone Asks About)

Once you know how the paper is structured, prepping for it gets a lot less intimidating. Here’s the breakdown.

Level 1 — Classes 1 to 4

Section	Questions	Marks Each	Total
Logical Reasoning	10	1	10
Mathematical Reasoning	10	1	10
Everyday Mathematics	10	1	10
Achievers Section	5	2	10
Total	35	—	40

It’s a pen-and-paper exam, 60 minutes, all MCQs, and conducted in English. One thing worth flagging to your child ahead of time: the Achievers Section questions are worth double, so those last five questions matter more than they look.

Level 2 — Classes 3 and 4

Section	Questions	Marks Each	Total
Mathematics	30	1	30
Achievers Section	5	2	10
Total	35	—	40

Level 2 drops the separate reasoning sections and goes straight for maths. It’s a more concentrated, tougher paper, which makes sense since it’s only for kids who already proved themselves in Level 1.

What's Actually in the Class 4 Syllabus

I like breaking this down for parents section by section, because it makes the prep feel far less overwhelming than “study everything.”

Logical Reasoning covers patterns, odd-one-out questions, geometrical shapes and solids, coding-decoding, ranking tests, direction sense, mirror images, embedded figures, analogy, classification, and questions around days and dates. This is the one section that genuinely feels different from schoolwork, so it deserves some dedicated practice on its own.

Mathematical Reasoning is the core maths portion of numerals, number names, number sense, the four basic operations, fractions, length, weight, capacity, time, money, geometry, symmetry, conversions, data handling, and perimeter. If your child is keeping up with their regular class, this section shouldn’t throw up many surprises.

Everyday Mathematics reuses the same topics as above but wraps them in word-problems form the kind of “if Ravi has 15 apples and gives away…” questions that test whether a child can actually apply what they know, not just recall it.

Achievers Section is where the harder, higher-order-thinking questions live, still based on the Mathematical Reasoning syllabus but pitched a level up. This is usually what separates the top rankers from the rest.

Because this Class 4 IMO math competition stays so close to the school curriculum, I generally tell parents: don’t panic and buy five extra workbooks. A calm, steady run through the topics above, plus some past papers, does the job.

How to Actually Sign Up

Registration for the International Math Olympiad class 4 exam almost always happens through the school, not directly by parents. In practice, it looks something like this:

Your child’s school (if it’s SOF-registered) will circulate a form, usually a few weeks before the exam window opens.
There’s a small registration fee collected along with the form schools handle this centrally.
Confirm the actual exam date with the school, since it’s one of the three dates SOF has announced.
If your school isn’t registered with SOF, individual registration is sometimes possible, generally up to around 15 days before the test date though I’d recommend checking SOF’s official website directly, since this kind of policy detail can shift year to year.

How to Actually Prepare (Without Overdoing It)

This is the bit parents care about most, so I’ll be honest and practical here.

Start with what your child already knows from school. That’s genuinely 70% of the battle for the IMO maths olympiad for class 4. From there:

Get your hands on a few previous years’ IMO Class 4 papers. Nothing builds familiarity with the question style faster than actually solving one.
Spend some separate time on Logical Reasoning specifically, since it’s the one area that doesn’t overlap much with regular classwork.
Don’t ignore the Achievers Section just because it’s only five questions; those ten marks add up fast.
Practise against the clock occasionally. Thirty-five questions in sixty minutes sounds like plenty of time until a child is actually sitting there second-guessing an answer.
Keep daily practice short. Twenty, maybe thirty minutes a day beats a stressed two-hour cram session on a Sunday.
A couple of proper mock tests in the last two weeks before the exam usually does more for a child’s confidence than another week of worksheets.

Results and What Kids Win

Results usually come out around January, though SOF treats this as tentative and confirms the exact date closer to the time. Top scorers can walk away with cash rewards of up to INR 50,000, gold medals, and performance certificates, and there’s a wider tier of rank certificates for students across school, zonal, and international levels so it’s not only the top one or two students who get recognised.

Conclusion

The IMO Maths Olympiad Class 4 isn’t the kind of exam that needs months of intense coaching; it rewards steady, consistent practice far more than last-minute cramming. If your child already has a decent handle on their Class 4 maths and puts in a bit of focused time on reasoning and a few past papers, they’re in a good position going in. And honestly, regardless of the rank they land, just going through the process tends to build a kind of confidence with numbers that sticks around long after the exam is over.

Frequently Asked Questions

Does my child need to study anything outside the school syllabus?

Not really. The content stays close to the regular Class 4 curriculum; it’s really the format and the reasoning questions that are new.

How long is the exam and how many questions does it have?

Level 1 has 35 questions for 40 marks, and students get 60 minutes to finish.

Does every Class 4 student get to attempt Level 2?

Is there negative marking?

As things currently stand, SOF doesn’t apply negative marking on IMO papers, but exam rules can be updated, so it’s worth a quick check on SOF’s official site before exam day just to be safe.
