What it is
The International Commerce Olympiad (ICO) is the Science Olympiad Foundation’s olympiad for commerce students in Classes 11 and 12. It is the only SOF olympiad that is just for the senior classes, and it is built around the commerce stream rather than science or maths.
It is a single-level olympiad. Students write one paper in school, and that paper decides their rank. SOF’s stated aim is to identify and foster a passion for commerce.
The paper has four sections:
| Section | Questions | Marks per question | Marks |
|---|---|---|---|
| Economics | 15 | 1 | 15 |
| Business Studies | 15 | 1 | 15 |
| Accountancy | 15 | 1 | 15 |
| Achievers Section | 5 | 3 | 15 |
| Total | 50 | 60 |
Topics on SOF’s syllabus include introductory microeconomics, the nature and purpose of business, business services and the accounting process, alongside the rest of the Class 11 and 12 commerce syllabus. The Achievers Section asks five harder questions worth 3 marks each. All questions are multiple choice, in English, and the paper lasts one hour.
Who can take it
Students in Classes 11 and 12 at schools registered with SOF, each writing the paper for their own class. It is written for commerce students; a student in another stream would find most of the paper outside their syllabus.
As with every SOF olympiad, entry is through the school only. Students cannot register individually, so a commerce student who wants to take part should ask their school’s olympiad coordinator or commerce teacher.
How it works
The school registers interested students with SOF at least 30 days before the date it has chosen. SOF offers two dates for this olympiad, and the school picks one; the date cannot be changed afterwards. The paper is written in school, during school hours.
SOF ranks students in each class internationally, by zone and within the school. For ties on total marks, SOF looks at section marks in a published order of priority, and students still level share the rank. SOF describes medals, certificates and other awards for top rank holders, and recognition for schools and teachers, on its official site.
When it happens
The ICO usually falls late in SOF’s year: one date is usually around late November or early December and the other in January. For Class 12 students, the January date can sit close to pre-board exams, so it is worth checking the school’s calendar before signing up. The exact dates for this year are on the official SOF page, and the olympiad calendar shows the usual months for every olympiad.
How to prepare
For a Class 11 or 12 student, olympiad preparation should strengthen board preparation, not compete with it. The ICO suits that well, because its three main sections are the three core commerce subjects.
Revise concepts, not just answers. Board papers reward complete written answers; an olympiad rewards knowing which of four options is exactly right. Re-read definitions closely: the difference between two similar business terms, or between two kinds of accounting entry, is often what a question turns on.
Practise applied questions. Many questions describe a small business situation and ask what follows. Working through examples in the textbook, and asking “what would change if…?”, builds this skill.
Keep accountancy practice short and accurate. Multiple-choice accountancy rewards careful working. A few problems a day, checked step by step, are worth more than a long session once a week.
Read the business news. A few minutes a day with the business pages helps economics and business studies questions feel concrete.
Time two papers. In the last three weeks, sit two SOF sample papers in one hour each. Fifty questions in sixty minutes leaves little time for long calculations, so spotting shortcuts matters.
Four to six weeks of light, regular work alongside school revision is usually enough. If the olympiad date clashes with school exams or board preparation, the board comes first.
Where daily practice fits
Ado does not cover commerce subjects, so it is not a way to prepare for this paper. Its free daily quiz of 8 questions, including a 60-second sprint, does keep maths, English, GK and reasoning sharp, with current affairs for older students, and ranks students only against others the same age. The Ado Rank builds from a student’s three strongest subjects and never resets, which makes it a small daily habit that sits easily beside board work.
Good to know
SOF’s other olympiads open to Class 11 and 12 students are its maths, science and English olympiads, all of which have two levels. A commerce student who takes maths in Class 11 or 12 may also be able to sit the maths olympiad. Outside SOF, SilverZone has announced its own ICSI-SilverZone Commerce Olympiad for Classes 11 and 12 from the 2026–27 session; details are on SilverZone’s site.
