How to Prepare for the Maths Olympiad (IMO): A Step-by-Step Guide
The International Mathematics Olympiad rewards reasoning, not memorisation. That is good news: with the right structure, almost any motivated student can improve dramatically. Here is a step-by-step plan you can follow without expensive coaching.
Step 1: Understand the exam pattern
A typical IMO Level 1 paper is split into clear sections:
- Logical Reasoning — patterns, series, analogies, spatial reasoning.
- Mathematical Reasoning — core concepts from your class syllabus.
- Everyday Mathematics — applying maths to real situations.
- Achievers Section — fewer questions, but each carries more marks. This section decides ranks.
Step 2: Map the syllabus to your class
The IMO syllabus closely tracks your school maths syllabus, one or two notches deeper. List every chapter for your class, and rate your confidence in each from 1 to 5. This single exercise tells you exactly where to spend your time.
Step 3: Build a realistic schedule
Consistency beats intensity. Twenty focused minutes a day for three months will outperform last-minute cramming every single time. A simple weekly rhythm that works:
- 3 days of topic practice (your weakest chapters first).
- 1 day of logical reasoning drills.
- 1 day reviewing mistakes from earlier in the week.
- 1 timed mini-test; rest on the seventh day.
Step 4: Learn from every mistake
Keep a “mistake log”. For each wrong answer, write one line on why it went wrong — careless error, concept gap, or misread question. Patterns appear within a week, and fixing them is the fastest way to gain marks.
Step 5: Take full timed mock exams
In the final month, sit at least two or three full-length, timed mock papers. This builds exam stamina, improves time management, and removes surprises on the big day. A good mock also predicts your likely rank so you know where you stand.

- Previous years’ sample papers from the official Olympiad body.
- Class textbook exercises — attempt the starred/optional problems.
- Pattern-aligned online practice that tracks your weak topics automatically.
The key is quality and pattern-fit, not volume. A hundred random sums help less than thirty well-chosen, exam-style questions reviewed properly.

How early should we start preparing for the IMO?
Two to three months of consistent, short daily practice is ideal for Level 1. Starting earlier helps, but regularity matters far more than the total number of hours.
Is coaching necessary to do well in the Maths Olympiad?
No. A structured plan, pattern-aligned practice, a mistake log and a few timed mock exams are enough for most students to perform well without paid coaching.
What is the Achievers section in the IMO?
It is a section with fewer but higher-mark questions that are more challenging. Because each question carries more weight, it heavily influences final ranks and deserves dedicated practice.
