What it is
SilverZone Foundation’s computer olympiad is called the International Computer Science Olympiad, and SilverZone writes it as iIO / iCSO. The iIO part comes from its earlier name, the International Informatics Olympiad. It is open to Classes 1 to 12 and has a single level: one paper, written in school.
SilverZone says the syllabus is based on what CBSE, ICSE and state boards teach in computer classes. The topics grow with the class:
- Classes 1–2: parts of a computer, uses of computers, keyboard and mouse, simple drawing and typing programs.
- Classes 3–5: hardware and software, Windows, word processing, presentations, spreadsheets, the internet and email.
- Classes 6–8: computer languages, algorithms and flowcharts, operating systems, number systems, computer viruses, and from Class 8, HTML, CSS, networks and cloud computing.
- Classes 9–10: information technology basics, networking, cyber safety and ethics, office tools, web page design, and in Class 9 an introduction to Python programming.
- Classes 11–12: computer fundamentals plus a programming section where students choose either Informatics Practices or Computer Science, in line with the two senior school subjects.
Every paper also has a Reasoning and Aptitude section. Up to Class 8 there is a Scholar’s Zone of harder questions too; from Class 9 the paper is computer science and reasoning only.
| Classes | Questions | Time |
|---|---|---|
| 1–2 | 25 | 40 minutes |
| 3–5 | 30 | 40 minutes |
| 6–8 | 35 | 40 minutes |
| 9–12 | 40 | 50 minutes |
Each paper is marked out of 100. Questions are multiple choice, answered on an OMR sheet, with no negative marking, and the paper is in English.
Who can take it
Students in Classes 1 to 12 whose school registers them with SilverZone. Any school can become a centre if enough students sign up; SilverZone sets the minimum. If your child’s school does not take part, the school can ask SilverZone for its prospectus.
How it works
The school registers students and picks one of SilverZone’s three dates. The paper is held in school, during school hours; SilverZone says the venue is the school only. With one level, there is no qualifying round: the Level 1 paper decides every rank.
SilverZone ranks students in each class across all participants in India and abroad, and by zone, state and class within the school. Every participant receives a chapter-wise performance report showing marks, ranks, percentiles and a breakdown by topic. SilverZone’s page says results are usually published on its website around February or March, and lists medals, certificates and other awards for top rank holders at each level.
When it happens
The paper is usually offered on dates between September and November, earlier than SilverZone’s maths, science and English olympiads. Schools usually register about 30 days before the date they choose. The exact dates are on the official SilverZone page, and the olympiad calendar shows the usual months for every olympiad.
How to prepare
Check the class syllabus against school. Not every school teaches the same computer topics in the same year. Go through SilverZone’s chapter list for your child’s class and tick what has been covered in school; the gaps are where to start.
Learn by doing. Questions on menus, shortcuts, file types and formulas are far easier for a child who has used the software. Twenty to thirty minutes a week with a word processor, spreadsheet or presentation tool, on a real small task, is worth more than reading about it.
For older students, write code. Small Basic appears in the syllabus from Class 6 and Python from Class 9. Writing and running short Python programs, and predicting what a few lines of code will print before running them, is good preparation for multiple-choice questions about code.
Keep reasoning in the mix. Reasoning and Aptitude carries a quarter or more of the marks in every class. Short puzzle sessions twice a week help; see the reasoning prep guide.
Answer every question. With no negative marking, a child should never leave an answer blank.
Three to five weeks of light preparation is enough for most children in the junior classes. Senior students should fit it around board and practical work, not on top of it.
Where daily practice fits
Computers are not one of Ado’s subjects, so the free daily quiz does not cover this paper’s main section. What it does build is reasoning, every day, alongside maths, science, English and GK: 8 questions a day, including a 60-second sprint. Students are ranked only against others the same age, and the Ado Rank builds from their three strongest subjects and never resets.
Good to know
SOF runs a separate olympiad with the same name, the SOF ICSO, for Classes 1 to 10. They are different organisers, papers and dates. SilverZone’s version is open up to Class 12; when a school mentions “the computer olympiad”, it is worth asking which one.
