UIMO runs on two separate tracks and they are not alternatives to each other. The 11 December paper is the school paper, written on school premises, and a school can only enter students for that one date — Unified Council publishes no second offline date for 2026-27. UIMO-online is a different sitting in January that a family enters directly; the 3 January date is its practice run, not the exam. Unified Council does not publish an application cutoff for either track.
Registration: For the December school paper, the school is the only route in: Unified Council states plainly that the venue is the school itself, that there is no open-centre facility, and that it does not accept individual application forms for UIMO. The school sends one consolidated list and demand draft; the fee is ₹150 per student. Because no cutoff is published, the honest advice is to ask your coordinator in October rather than work backwards from December. If your school does not run UIMO at all, you are not locked out — UIMO-online on 10 January takes direct registrations from families at ₹354 including GST, is written at home on a laptop with a webcam, and uses the same Classes 6 to 10 paper structure.
The deadline is set by your school, not by you
Most parents find the exam date and assume they have until then. The registration window closes long before it, and for some papers it has already started closing. Here is how it actually works.
- Your school registers your child and your school picks which of the 2–3 dates the class sits. The family does not choose.
- For SOF papers, registrations must reach SOF exactly 30 days before that chosen date — and once the school has chosen, the date cannot be changed.
- Most bodies register through the school. These do not have to: CREST (online, no published cutoff), Unified Council — directly for NSTSE itself at ₹350 against ₹150 through a school, and on three online sittings, NSTSE-Online, UIMO-Online and UIEO-Online, at ₹354 each including GST — Indian Talent Olympiad on its individual online route (its own later dates — Slot 1 closes 30 October), and Humming Bird (online, ₹150 a subject, no published cutoff — its two dates are picked as you register). CREST is the simplest of them. SilverZone also runs an individual registration form alongside its default school route; which papers it offers we have not been able to confirm.
Closing next
SOF IEO (English) — if your school picks 27 October 2026
Registrations must reach SOF by 27 September 2026
SilverZone Foundation — Every SilverZone paper
Registration closes 30 September 2026
The body publishes this date but has not marked it final — confirm with your school before treating it as fixed.
SOF ISO (Science) — if your school picks 30 October 2026
Registrations must reach SOF by 30 September 2026
Indian Talent Olympiad (ITO) — School route — Set B
Registration closes 10 October 2026
SOF IHO (Hindi) — if your school picks 23 November 2026
Registrations must reach SOF by 24 October 2026

Exam pattern
How the UIMO paper is structured
| Section | Questions | Marks per question | Section total |
|---|---|---|---|
| Mathematics - 1 (single correct answer) | 30 | 1 | 30 |
| Mathematics - 2 (multiple correct answers, Q31-35) | 5 | 3 | 15 |
| Logical Reasoning | 10 | 1 | 10 |
| Critical Thinking | 5 | 1 | 5 |
| Total | 50 questions | — | 60 marks · 60 minutes |
The paper is 50 questions for 60 marks — the extra 10 marks come from Mathematics-2, where each of the five questions is worth 3. Unified Council states that every question is objective-type with no negative marking for a wrong answer, so a blank scores exactly what a wrong answer scores: nothing. It publishes no current-year versus previous-year split for UIMO, unlike SOF, so treat the whole Class 6 book as live.

Two things about this paper are worth more than the chapter list. First, Mathematics-2 is not a harder version of Mathematics-1 — it is a different question type. Five questions, numbered 31 to 35, have more than one correct option (two, three or four of them can be right), and a child has to darken every correct one on the OMR sheet to earn the 3 marks. That format barely appears in school tests, and it is 15 of the 60 marks. Second, five topics that Class 6 olympiad papers still draw on are not in the 2026-27 Ganita Prakash book at all: Roman numerals, ratio and proportion with the unitary method, the introduction to algebraic expressions, simple one-variable equations, and the recognition of 3-D solids and their faces, edges and vertices. All five sat in the previous Class 6 NCERT, and they went to four different places. Ratio and proportion with the unitary method is the one our curator taxonomy carries as a Class 6 olympiad-scope topic beyond the book, and our Class 6 maths practice keeps it in scope. Algebraic expressions and simple one-variable equations moved up one year and are Class 7 chapters now — Expressions using Letter-Numbers, and Finding the Unknown. The recognition of 3-D solids with their faces, edges and vertices moved up two, into Class 8's Exploring Some Geometric Themes. Roman numerals are the only one with no home in the Classes 6 to 8 spine at all; the nearest thing to them is Class 8's A Story of Numbers, which is about numeral systems in general. So four of the five are still worth practising for this paper, but a parent should know they will not find four of them in this year's book. Separately, Logical Reasoning (10 marks) and Critical Thinking (5 marks) are their own spine — a quarter of the paper that no maths chapter feeds.

Guides that answer the next question
The registration deadline has passed — can my child still sit an olympiad?
A closed olympiad deadline is almost never the season closing. Of the three routes due to close on 31 August 2026, only SOF’s actually did — SilverZone moved its cutoff to 30 September and Indian Talent Olympiad extended Set A twice, to 10 September. Twelve of SOF’s thirteen sittings in Maths, Science, English, Hindi and Social Science were never on that clock at all, and some bodies take a registration straight from a family. Here is what is still open, subject by subject, with the date each route closes on.
SOF IMO vs SilverZone iOM: which should your Class 6 child take?
SOF IMO and SilverZone iOM both test Class 6 maths, but the exam pattern, syllabus split, and scoring are different enough to matter. Here is a side-by-side comparison to help you choose — or why most families end up doing both.
