Olympiad Exam 2026–27: Dates Students & Parents Can Actually Use
A practical calendar for SOF, SilverZone and Unified Council exams. Instead of showing a long list of dates without context, this page explains which date your child should follow, where schools choose between multiple sittings, and what to check before the exam.
Verified 21 September 2026 • Dates may be school-selected for some Olympiads
How to use this calendar without getting confused
Many Olympiad bodies publish more than one date. That does not always mean the student can freely choose any date. In school-based Olympiads, the school normally confirms the sitting it is conducting.
The next dates to check first
These are the nearest published SOF sittings from the current date. If your school has already issued a circular, use the school-confirmed date for your child.

Official checks: Unified Council registrations and exam schedule
Before you mark the exam date on the family calendar
School circular is the practical final check
For school-conducted Olympiads, a published list may contain several dates. The school notice tells you which sitting your child is actually being entered for.
Keep the organiser page bookmarked
If an organiser updates dates, the live official page is more reliable than an old screenshot or forwarded message.
Do not mix offline and online schedules
Unified Council, in particular, separates offline school exams from online final exams. Confirm the registration mode first.
Need help preparing after the date is confirmed?
For syllabus, preparation support or current batch information, use the dedicated Olympiad page or speak to the South Extension team. This keeps the calendar informational while giving parents a clear next step when they need academic support.
Registration mode checked?
Syllabus matched?
Questions parents usually ask about Olympiad dates
Can a student choose any SOF date?​
Usually no. SOF publishes multiple dates, but the school selects the sitting it conducts. Follow the date confirmed by your school.
Why do some 2026–27 exams continue into 2027?​
The academic-session calendar runs across two calendar years. Some online exams and second-level exams therefore fall in January or February 2027.
What should I do if the school circular and website do not match?
Ask the school coordinator to verify the current official sitting before the exam. Do not rely on an old screenshot or forwarded message.
Are SilverZone dates likely to change?
SilverZone maintains a live schedule. Re-check the official page and your school notice near the exam date, especially if you saved the calendar earlier.
