🧾 The IMO paper at a glance

Level 1 pattern — 50 questions, 60 marks, 60 minutes.

Section Questions Marks each Total
🧩1 · Logical Reasoning
Patterns, coding, mirror images, directions
15 1 15
🔢2 · Mathematical Reasoning
Numbers, fractions, geometry, measurement
20 1 20
🛒3 · Everyday Mathematics
The same maths, inside real-life word problems
10 1 10
🧠4 · Achievers Section
Higher order thinking — worth 3 marks each!

🚀 How toppers prepare for the IMO

🧠 Understand the concept, don't memorise steps

Olympiad questions are twisted on purpose. If you only memorised a method, a small twist will break it. Always ask "why does this work?"

📓 Keep a formula & trick notebook

One page per topic: the rule, one solved example, one mistake you made. Read it the night before the exam instead of a fat book.

⏱️ Practise with a clock

50 questions in 60 minutes is a little over a minute each. Take the mock tests here with a timer beside you.

✍️ Always use rough paper

Write the gaps under a number series. Write the alphabet before a coding question. Mental maths alone causes silly mistakes.
