Indian Talent Olympiad Maths Olympiad (IMO) Class 6: syllabus, dates and exam pattern (2026–27)

Two different calendars sit above, and which one applies to your child depends on how they are entered. The three Set dates are the school route: the school picks one set, and the child sits the paper with the class. The two slot dates are the individual online route a family can take without the school — different dates entirely, and Indian Talent Olympiad publishes them with the caveat that they are tentative and that "the final exam schedule will be updated 20 days prior". Once a set or slot is selected it cannot be changed.

Registration: Registration closes on published, fixed dates rather than a rolling window — Indian Talent Olympiad is one of only three bodies we cover that publishes cutoffs at all, alongside SOF (which publishes the rule rather than the date) and SilverZone (30 September 2026, every paper). Through the school there are three windows, and which one applies depends on the date you read this: Set A's cutoff was 10 September 2026 and has passed, Set B's is 10 October 2026 and Set C's is 10 November 2026. Set A moved twice before it closed, from 31 August to 5 September and then to 10 September, each time announced only by the date changing on the schedule page, which still reads "LAST DATE TO REGISTER – SET A Extended Till 10 th September, 2026" — so treat the two later dates as figures ITO can move too. The school collects ₹175 per student per subject, of which ₹150 is remitted to ITO and ₹25 is retained for organising costs. Directly, without the school: individual online registration for Classes 1 to 10 closes 30 October 2026 for slot 1, at ₹500 per subject. That direct route matters more than it sounds — most bodies register only through the school, and we have confirmed direct routes at CREST (online, no published cutoff), Unified Council's NSTSE (₹350 direct), Humming Bird (online, ₹150 a subject) and this one. Those three are the school route; the individual online route's 30 October 2026 is a separate clock from all three — a school that missed a Set does not cost the family the direct route, and the direct route closing does not extend a Set. Two things about that school deadline that ITO's schedule page does not say and its fee page does. First, it is a POSTAL deadline: the completed registration form, the student list and the fee as a demand draft have to reach Indian Talent Olympiad's Mumbai office by the cutoff, by registered post or courier, so the envelope has to leave the school several days before the cutoff rather than on it. Second, the two pages disagree — the fee page still instructs schools to send everything to arrive "on or before 31st August 2026 (Slot 1)", the date the body has since moved off twice, and it calls the three windows Slot 1, 2 and 3 where the schedule calls them Set A, B and C. The two pages agree on the later two windows — the fee page's Slot 2 (10 October 2026) and Slot 3 (10 November 2026) are the schedule page's Set B and Set C — so the disagreement is confined to the window that closed first. Both pages were read first-hand on 12 September 2026. Ring the body before your school posts a draft.
