If you've heard your child's school mention IMO, NSO, or IEO registration and weren't quite sure what any of it meant, this page is for you. Everything below is based on the current, publicly published exam patterns for the 2026-27 cycle.
Olympiad exams are optional, school-registered competitive tests, run by independent organisations, not CBSE itself, that go a level deeper than the regular school syllabus. The most common ones for Class 6 and 7 are run by the Science Olympiad Foundation (SOF): the International Mathematics Olympiad (IMO), the National Science Olympiad (NSO, recently folded into ISO), and the International English Olympiad (IEO). The syllabus is drawn from the CBSE curriculum your child is already studying, but the questions are written to test reasoning and application, not recall.
These are not CBSE exams. CBSE sets the school curriculum; these are independent bodies that build competitive tests on top of it.
The most widely written Olympiad body in Indian schools. Runs IMO (Maths), ISO, formerly NSO (Science), IEO (English), and IGKO (General Knowledge), each open to Class 1 through 12, with two difficulty levels for most subjects.
Silverzone, Unified Council, and a handful of state-level bodies also run similar competitive exams. The structure varies by organiser, but the core idea is the same: an objective, timed paper built on the school syllabus, with a harder, application-heavy edge.
Using SOF's IMO (Maths) as the reference, since it's the most widely written. The shape is broadly similar across NSO/ISO and IEO too.
| Section | What it tests | Questions |
|---|---|---|
| Logical Reasoning | Pattern recognition, coding-decoding, non-verbal reasoning | 15 |
| Mathematical Reasoning | Core class-syllabus Maths, applied at a harder level | 20 |
| Everyday Mathematics | Real-world application of the same concepts | 10 |
| Achievers Section | Higher-order thinking, worth more marks per question | 5 |
For Class 5 and above, that's 50 questions in 60 minutes for 60 marks, all multiple-choice, no negative marking. Level 1 draws roughly 60% of its questions from the current class syllabus and 40% from the previous class, so a Class 7 student will still see some Class 6 material. The Achievers Section is the one exception, it's drawn entirely from the current class.
| Olympiad | Subject | What it's really testing |
|---|---|---|
| IMO | Mathematics | Logical and mathematical reasoning, applied problem-solving |
| NSO / ISO | Science | Concept application across Physics, Chemistry and Biology topics for the class |
| IEO | English | Grammar, vocabulary, comprehension and real-world usage |
The Mathematical and Everyday Mathematics sections draw directly from the current NCERT chapters: for Class 6, that's Patterns in Mathematics, Lines and Angles, Number Play, Data Handling and Presentation, Prime Time, Perimeter and Area, Fractions, Playing with Constructions, Symmetry, and The Other Side of Zero. For Class 7, the syllabus builds on this with more advanced geometry, integers, and algebraic thinking. The Logical Reasoning and Achievers sections sit outside the textbook entirely, they reward pattern recognition and applied thinking built through practice, not memorisation.
Our approach at The67Sprint: Step Beyond includes ten full-length Olympiad-style papers for each of Maths, Science, Social Science, English and Cyber, for both Class 6 and Class 7, with every answer explained, not just marked right or wrong. Every paper is also available as a timed online quiz that scores you instantly. See the full Step Beyond library.
