SOF IMO Class 6: syllabus, paper pattern and sample questions
The SOF International Mathematics Olympiad for Class 6 is a 60-minute paper of 50 questions for 60 marks in 4 sections. Every question has four options and one right answer. The last 5 questions are the Achievers Section, worth 3 marks each. Below: how the paper is set out, the 12 chapters it draws on, one sample question from each section with its answer, and how to practise it for free.
Paper pattern
IMO Class 6 is set out in 4 sections. Sprinto's mock tests and printed papers follow the same order, counts and marks.
| Section | Questions | Marks each | Marks |

| 1.Logical Reasoning | 15 | 1 | 15 |
| 2.Mathematical Reasoning | 20 | 1 | 20 |
| 3.Everyday Mathematics | 10 | 1 | 10 |

Syllabus: the 12 chapters
Every question on the paper belongs to one of these chapters. On Sprinto's map each chapter is an island, and the Achievers Section is the same chapters asked harder — not a separate topic.

Sample questions with answers
One from each section, taken from Sprinto's own bank for IMO Class 6. In the app the numbers, names and figures are different every time; these are fixed so you can read them.
Sample 1 · Section 1: Logical Reasoning · Figure Reasoning
Answer: (A)
A mirror held at the side swaps left and right but keeps top and bottom the same way up.
Sample 2 · Section 2: Mathematical Reasoning · Lines and Angles
Two angles are supplementary. One of them is 79°. What is the other one?
Answer: (A) 101°
Supplementary angles add up to 180°, so the other angle is 180° − 79° = 101°.
Sample 3 · Section 3: Everyday Mathematics · The Other Side of Zero
At noon the temperature in Gulmarg was 10 °C. By midnight it had fallen by 19 °C. What was the temperature at midnight?
Answer: (D) −9 °C
10 − 19 = −9, so it was −9 °C at midnight.
Sample 4 · Section 4: Achievers Section · Figure Reasoning · Achievers difficulty
Find the total number of squares of every size in the given figure.
Answer: (A) 50
Adding up the squares of each size, 24 + 15 + 8 + 3 = 50.
How to practise IMO Class 6 on Sprinto
- One island per chapter. A hidden rating per chapter picks the next maths question at the difficulty that is just hard enough today.
- Mistakes come back. Anything she gets wrong returns a few days later, then a week, then a month, until it stops being a mistake.
- Mock tests in the real shape. 50 questions, 4 sections, 60 minutes, marked the moment she hands it in.
- Papers you can print. A full IMO Class 6 paper with an OMR sheet, sat at the table with a pencil.
Free, with no ads and nothing to buy. A parent signs in with Google once; the child taps her face and starts.
