Hi

The International English Olympiad (SOF IEO) is an annual competitive exam which was designed to test students' knowledge. This exam is conducted by the Science Olympiad Foundation (SOF) in collaboration with the British Council. This exam is held on 26th September, 11 November, and 26th November, which helps students to learn something new. If you want to download the question paper, then please read the article SOF IEO 2025 Question Paper 2025 , which was published on our official website, careers360.

Thank you.

The SilverZone Olympiad dates for December 2025 have not been officially announced yet. SilverZone usually releases its exam schedule a few months before the exam cycle, so students need to wait for the updated notification from the organisation or check with their school, as most Olympiad registrations and exam dates are managed through schools.

Regarding the question paper set, SilverZone typically provides different sets for different exam dates to maintain fairness. The exact set you will receive cannot be known in advance, as it is assigned by the organisation and varies by school and exam slot. Your focus should be on preparing the full syllabus rather than expecting a specific set.

All the best.
