This blog gives you the correct schedule, the main exam windows, and the best way to prepare using practice material like StudyNexa Olympiad Digital Resources.

SOF Olympiad exam dates 2026–27

According to the official SOF schedule, schools may select one date for each exam, and change of date is not permitted. For FY 2026–27, the official dates shown for the major Olympiads include the following.

• IEO: 30 September 2026, 27 October 2026, 17 November 2026.
• IMO: 23 October 2026, 26 November 2026, 10 December 2026.

SOF has also said that second-level exams for IEO, ISO, and IMO will be announced later and are tentatively expected on the 2nd or 3rd Sunday of February 2027.

Olympiad exam timings

For many Olympiads, the exact timing depends on the school or exam platform rather than being the same for all students. SOF’s official schedule mainly confirms the date selections, while other Olympiad organizers may publish time slots directly on their portals.

For example, some exam platforms publish online slots between 11 AM and 7 PM IST depending on the selected time window. So if your child is appearing through school, the school’s chosen date and internal arrangement decide the exact time.

How to prepare before the exam

The best way to prepare is to practice with question banks, sample papers, and previous-year style questions instead of only reading theory. That is exactly where StudyNexa Olympiad Digital Resources can help.

A simple preparation routine:

• Solve one practice set daily.
• Focus on one subject at a time.
• Review mistakes immediately.
• Use chapter-wise revision in the last 2 weeks.
• Take at least 3 full mock tests before exam day.

For students preparing for IMO and IEO, structured practice matters even more because these Olympiads test speed, concept clarity, and accuracy.

Best resources for students

If you want a practical resource instead of theory-heavy books, use the following:

• StudyNexa Olympiad Digital Resources for Class-wise Olympiad practice.
• Olympiad question banks for daily revision.olympiad.
• Sample papers and previous-year papers for pattern understanding.
• Online mock tests for speed and accuracy practice.

If your child is targeting IMO or IEO, practice material should be used regularly, not only near the exam. That is why StudyNexa Olympiad Digital Resources is a useful preparation option.

What parents should remember

Parents usually search for dates, but the bigger win is early preparation. Olympiad schedules are spread across multiple dates, which gives students enough time to revise properly if they start early.

The safest plan is to:

• confirm the school-selected exam date,
• prepare with a fixed weekly routine,
• and use StudyNexa Olympiad Digital Resources for repeated practice.

For FY 2026–27, the most important official dates are already published for SOF Olympiads, while level 2 dates will be announced later. If you want better performance, combine the schedule with regular practice using StudyNexa Olympiad Digital Resources and a structured mock-test plan.
