IMO — International Maths Olympiad (SOF)

IMO (International Mathematics Olympiad) by SOF is a prestigious maths competition for Classes 1–12. It tests mathematical reasoning, problem-solving, and logical thinking through challenging MCQs.

Note: This is the SOF IMO, distinct from the International Mathematical Olympiad organized by IMO Foundation.

• Level 1: 35 MCQs (Classes 1–4) or 50 MCQs (Classes 5–12)
• Duration: 1 hour | Mode: Offline OMR at school
• Sections: Mathematical Reasoning + Logical Reasoning + Achievers Section
• Level 2: Top 5% per class per zone qualify
• No negative marking

• Classes 1–5: Numerals, Arithmetic, Geometry basics, Patterns, Measurement, Data Handling
• Classes 6–8: Number System, Algebra, Geometry, Mensuration, Data Handling, Ratio & Proportion
• Classes 9–10: Polynomials, Coordinate Geometry, Trigonometry, Statistics, Probability, Circles
• Classes 11–12: Sets, Relations, Calculus, Matrices, Probability, 3D Geometry

• Builds JEE Maths foundation: Strong problem-solving skills directly help in JEE/competitive maths
• Develops speed & accuracy — critical for board exams and entrance tests
• Awards: Cash prizes, gold/silver medals, certificates at zonal, state, and international levels
• Performance report: Detailed topic-wise analysis helps identify weak areas
• Resume builder: IMO achievements strengthen school/college applications
• Parent insight: Performance report gives parents clear visibility into child's math aptitude
