IMO Class 10 Syllabus 2026-27: SOF Maths Olympiad Topics & Exam Pattern

Class 10 students answer 50 questions for 60 marks in 60 minutes. The paper includes Logical Reasoning, Mathematical Reasoning, Everyday Mathematics and the Achievers Section.

Yes. In Level 1, approximately 60% of questions come from the Class 10 syllabus and 40% from the Class 9 syllabus.

The Level 2 syllabus is based on the current Class 10 syllabus only. Previous-class topics are not included in the Level 2 syllabus.

There are 50 questions in Level 1 and 50 questions in Level 2 for Class 10.

Both Level 1 and Level 2 carry 60 marks.

The Achievers Section contains 5 Higher Order Thinking questions based on the current Class 10 Mathematical Reasoning syllabus. Each question carries 3 marks.

Yes. Introduction to Trigonometry and Some Applications of Trigonometry are included in the official Class 10 syllabus.

Yes. Probability is one of the prescribed Mathematical Reasoning topics for Class 10.

No. SOF states that its syllabus takes into account CBSE, ICSE and various state-board curricula, with syllabus changes or reductions reflected in actual question papers.

NCERT is useful for building strong concepts, but students should also practise Olympiad MCQs, reasoning questions, sample papers, previous year papers and HOTS questions.

Students should prepare the complete syllabus, but chapters such as Quadratic Equations, Arithmetic Progressions, Coordinate Geometry, Trigonometry, Circles, Mensuration, Statistics and Probability require strong application skills.

Level 1 includes approximately 60% Class 10 and 40% Class 9 syllabus, while Level 2 uses only the current Class 10 syllabus.

There are 5 Achievers Section questions, each carrying 3 marks.

Everyday Mathematics tests application of Mathematical Reasoning and Quantitative Aptitude concepts in practical or problem-solving situations.

Revise important Class 9 Mathematics concepts and practise application-based questions because around 40% of Level 1 questions may come from the previous class syllabus.

The topics are largely class-appropriate, but the questions can be more analytical and application-oriented than routine school exercises. HOTS and Achievers Section questions require especially strong conceptual understanding.

Students can refer to the official SOF Class 10 syllabus page and the 2026-27 sample paper PDF, which contains the current syllabus and marking scheme.

The official marking scheme lists marks awarded per question and does not specify negative marking.

Complete the syllabus chapter-wise, revise Class 9 concepts for Level 1, practise Logical Reasoning and HOTS questions, solve previous papers and take timed mock tests regularly.
