Before you message
How do I reach you?
Scan the WeChat QR above to add an advisor, or message us on WhatsApp. Both are checked daily.
Is there a fee to enter the IEO?
Participation in the official Olympiad is free of charge. Guidance from us is a separate, optional service.
Which year groups can compete?
High-school students under 20 on 30 June of the competition year. It’s fine to start preparing a year or two ahead.
