Preparing for IOQM 2025? The difference can be made by the right source of study blog will give you a carefully selected list of the study material for IOQM 2025, online sources, and practice sources so that you may survive the Indian Olympiad Qualifier in Mathematics (IOQM) with confidence.

IOQM Books

Indian Olympiad Qualifier in Mathematics (IOQM) is a very difficult process that most students like to solve difficult math problems. The IOQM is the gateway for many students to compete at the international level (at INMO and IMO), where not only speed and accuracy are not enough, but conceptual understanding and creative thinking skills are needed too. Getting the correct IOQM study material also becomes a major concern in your preparation process.

When you are in class 8 and learning about the maths olympiad, or a class 11 student wishing to crack the IOQM examination, then the materials you select can make or even destroy your preparation. However, there are so many IOQM book PDF free downloads, video materials, and practice tests that it becomes confusing. This is the reason why this blog gives you a structured and carefully selected list of the best study material for IOQM 2025 in various topics and classes according to their difficulty levels and the goal of your preparation. 

IOQM Exam Details

The Indian Olympiad Qualifier in Mathematics ( IOQM ) is the introductory round in the India national-level mathematical Olympiad system run by the Mathematical Olympiad Cell (MO Cell), in cahoots with the Homi Bhabha Centre for Science Education (HBCSE) and the National Board of Higher Mathematics (NBHM). It acts as a gateway for those high school students who are planning to excel at the esteemed International Mathematical Olympiad (IMO). In this blog, we are going to share the study material for IOQM 2025, which is very useful for your IOWM preparation.

The two-stage mechanism (PRMO and RMO) was replaced by a one-stage selection test called OQM, which is an elimination test to make it to the INMO (Indian National Mathematical Olympiad). It is one of the most competitive exams and challenges not only with the content covered at school in math, but also calls upon reasoning and logical thinking, especially at the higher levels.

  • Eligibility: Class 8 to 12 
  • Level: National
  • Duration: 3 hours
  • Question Type: both short and long

How to make a study Plan for IOQM 2025?

To organize a successful preparation strategy for IOQM, it is necessary to combine the Olympiad preparation with school studies, successfully balancing two directions. The first step is becoming aware of the syllabus, breaking topics into weekly objectives and dedicating some time to revision and practice tests. Here is the list of how to prepare for IOQM 2025:

4-Week Smart Study Plan for IOQM 2025

Week Main Focus What to Do Your Goal
Week 1 Number Theory - Revise basics: divisibility, remainders, congruence
- Solve 20+ practice problems
- Attempt 1 mock test
Build a solid foundation in number skills
Week 2 Algebra & Equations - Practice identities, linear & quadratic equations
- Watch 2 concept videos
- Solve past IOQM problems
Strengthen algebraic thinking
Week 3 Geometry & Coordinate Geo - Focus on angles, triangles, area & midpoints
- Practice diagrams and visualization
- Solve 2 Qs daily
Improve visual & spatial reasoning
Week 4 Combinatorics & Reasoning - Learn permutations, combinations, and logic puzzles
- Take 2 full mock tests
- Review mistakes deeply
Master problem-solving strategies

Must do in weekly basis:

  • Study one to two hours per day
  • Play the game IOQM Question of the Day
  • Full-length mock tests and revision should be used during weekends.
  • To keep track and cover again on weak topics

IOQM Practice Strategy

  • Before Reading
    • To develop clarity in concepts, begin with reliable texts such as Challenge and Thrill of Pre-College Mathematics or the IOQM guide from Class24.
  • Take Practical Examples
    • Follow each idea by working on solved examples to get an idea of how the theory can be used in a variety of problems.
  • Practice Problems Topic-Wise\
    • Solvers for multiple problems of Number Theory, Algebra, Geometry, and Combinatorics have been solved in a systematic, topic-wise way.
  • Monitor and Achieve Poor Performance
    • Write out errors and concepts that you find hard in an IOQM book PDF free Download, then read them and rehearse them frequently to improve on weak areas.
  • Sign up with a Mock Test Series
    • By taking full-length weekly tests and timed sectional quizzes, simulating real exam conditions, speed and accuracy will be developed.
  • Analyse all the Tests
    • Check how you perform after each of the tests to see what kind of mistakes you make and not repeat them in the future.
  • IOQM Previous Year Question Paper
    • One of the smartest things to do when preparing for the IOQM previous year question papers (PYQs). It aids the students in getting familiar with the pattern, the difficulty level, and the more common topics to be covered in the exam, which leaves them with a definite advantage in terms of preparation.

IOQM PYQs can be found at:

  • Olympiad by Class24 App Download- Exam Prep PYQs (topic-wise), high-quality complete solutions and answers
  • Mock Test Series -This is similar to the IOQM tests that use the actual IOQM Previous Year question Paper PDF Download

How PYQs Help You?

  • Become familiar with some of the more frequently tested topics in Number Theory, Algebra, Geometry, and Combinatorics
  • Find out the weightage of each topic and work accordingly on preparation priorities
  • Increase perfectness and quickness by training in time-limited circumstances
  • Our categorized PYQ bank can enable the students to focus their preparation in a smart way and practice where practice is most important.

Topic-Wise PYQ Mapping 

Topic Source Sample PYQ Type
Number Theory IOQM 2022 Remainder theorem, divisibility
Algebra RMO 2019 Quadratic identities, expressions
Geometry INMO 2021 Cyclic quadrilaterals, circles
Combinatorics IOQM 2023 Counting principles, arrangements

Pro Tip: You should solve PYQs when you have a clear preparation of the basics, and consider them a part of your revision regime, to revise once a week.

FAQs

IOQM (Indian Olympiad Qualifier in Mathematics) is the first stage for selection in the Indian Mathematical Olympiad Program.

It is jointly conducted by MTA (India) and HBCSE under NBHM.

Indian students born on or after August 1, 2004, and studying in Classes 8–12.

Topics include Number Theory, Algebra, Geometry, and Combinatorics—mostly up to Class 10 level, but Olympiad-standard.

Typically, 24 questions—mostly integer and subjective-type.

No negative marking in IOQM.

Use NCERTs, Olympiad books, topic-wise PYQs, and join test series like those on Olympiad by Class24 App.

Top scorers qualify for INMO (Indian National Mathematics Olympiad).

On the HBCSE website or apps like Olympiad by Class24, with topic-wise solutions.

Not mandatory, but structured guidance and regular practice improve your chances significantly.
