SOF IMO Class 11 Syllabus – Complete Applied Mathematics Topics PDF Download

The IMO Class 11 syllabus 2026-27 covers advanced Mathematics and reasoning topics that test conceptual understanding, analytical ability and problem-solving skills. Students preparing for the SOF IMO need to study topics such as Sets, Relations and Functions, Complex Numbers, Quadratic Equations, Sequences and Series, Trigonometry, Straight Lines, Conic Sections, and more.

Students following Applied Mathematics have an alternative prescribed topic set. The IMO Olympiad syllabus Class 11 is divided into Logical Reasoning, Mathematical Reasoning or Applied Mathematics, Everyday Mathematics and the Achievers Section.

Level 1 contains 50 questions for 60 marks and has a duration of 60 minutes. Around 60% of Level 1 questions come from the current Class 11 syllabus and 40% from the previous Class 10 syllabus, while Level 2 questions are based on the current class syllabus only.

Class 11 IMO Syllabus 2026-27 – Section-wise Topics

Logical Reasoning	Verbal and Non-Verbal Reasoning	15	1	15
Mathematical / Applied Mathematics	Sets, Relations & Functions, Logarithms, Complex Numbers, Quadratic Equations, Inequalities, Sequences & Series, Trigonometry, Straight Lines, Conic Sections, P&C, Binomial Theorem, Statistics, Limits & Derivatives, Probability, 3D Geometry; or prescribed Applied Mathematics topics	20	1	20
Everyday Mathematics	Quantitative Aptitude	10	1	10
Achievers Section	Advanced class-specific mathematical concepts and HOTS	5	3	15
Total	—	50	—	60

IMO Syllabus Class 11 Mathematical Reasoning Topics

Students choosing the Mathematics route should prepare the following topics:

Topic Area	Topics Included
Sets and Functions	Sets, Relations and Functions
Algebra	Logarithms, Principle of Mathematical Induction, Complex Numbers, Quadratic Equations, Linear Inequalities
Sequences	Sequences and Series
Trigonometry	Trigonometric concepts and applications
Coordinate Geometry	Straight Lines and Conic Sections
Combinatorics	Permutations and Combinations
Algebraic Expansion	Binomial Theorem
Statistics	Statistical concepts
Calculus	Limits and Derivatives
Probability	Probability
3-D Geometry	Introduction to Three-Dimensional Geometry

These topics form the core Mathematics route in the syllabus of IMO Class 11.

IMO Class 11 Applied Mathematics Syllabus

Students following Applied Mathematics can prepare the alternative Section 2 syllabus prescribed by SOF.

Topic Area	Topics Included
Numerical Concepts	Numbers, Quantification, Numerical Applications
Sets and Functions	Sets, Relations and Functions
Sequences	Sequences and Series
Combinatorics	Permutations and Combinations
Reasoning	Mathematical Reasoning
Calculus	Limits, Continuity and Differentiability
Probability	Probability
Statistics	Descriptive Statistics
Financial Mathematics	Basics of Financial Mathematics
Coordinate Geometry	Straight Lines, Circle and Parabola

SOF lists this Applied Mathematics route as an alternative to the standard Mathematical Reasoning syllabus for Class 11.

SOF IMO Level 1 Syllabus for Class 11

The SOF IMO Level 1 syllabus follows a mixed current-class and previous-class pattern.

Syllabus Coverage	Approximate Weightage
Class 11 Syllabus	60%
Class 10 Syllabus	40%
Achievers Section	Class 11 syllabus only

This means students should not prepare only Class 11 topics. Revising important Class 10 Mathematics concepts is also necessary for Level 1.

SOF IMO Level 2 Syllabus for Class 11

The Level 2 syllabus is based on the current Class 11 syllabus only. Previous-class topics are not included at this stage.

IMO Class 11 Achievers Section Syllabus

The Achievers Section is important because each question carries 3 marks. For Class 11, SOF lists the following high-level areas:

Sets, Relations and Functions
Sequences and Series
Permutations and Combinations
Limits and Derivatives
Straight Lines
Circle
Parabola
Probability

The section contains 5 Higher Order Thinking Skills questions for a total of 15 marks.

The 2026-27 official SOF Class 11 sample paper confirms this SOF IMO exam pattern.

Which Topics Need More Focus for IMO Class 11?

Students should cover the complete syllabus because SOF does not publish a fixed chapter-wise weightage. However, some areas require stronger conceptual application and regular problem-solving practice:

Complex Numbers and Quadratic Equations
Sequences and Series
Trigonometry
Straight Lines and Conic Sections
Permutations and Combinations
Binomial Theorem
Limits and Derivatives
Probability
Sets, Relations and Functions

The goal should be to understand concepts deeply rather than memorise formulas, especially for Achievers Section questions.

How to Prepare for IMO Olympiad Syllabus Class 11?

Class 11 IMO preparation should balance board-level concepts with Olympiad-style application.

Complete the Class 11 Maths or Applied Mathematics syllabus systematically.
Revise important Class 10 concepts for Level 1.
Practise verbal and non-verbal reasoning regularly.
Solve chapter-wise Olympiad MCQs after concept revision.
Give extra attention to Limits, Probability, P&C, Sequences and Coordinate Geometry.
Practise Achievers Section HOTS questions.
Solve previous-year IMO papers.
Attempt 60-minute mock tests to improve speed and accuracy.

SOF’s current Class 11 workbook includes chapter-wise MCQs, HOTS practice, explanations and the latest previous-year paper for structured preparation.
