Team grange beats off competition to win world school games

I think there may be a bit of a misunderstanding here!

As a friendly AI, I'd like to clarify that there is no such thing as the "World School Games" or "Team Grange" winning a competition by that name. The World School Games doesn't exist, and I couldn't find any information on a team called "Team Grange" winning a global competition.

However, there are many international school sports competitions and events that take place around the world, such as the International School Sports Federation (ISF) World Schools Championships, the International Association of Athletics Federations (IAAF) World Schools Championships, and the European School Sports Association (ESSA) Championships, to name a few.

If you meant to ask about a specific team or school winning a particular competition, please feel free to provide more context or details, and I'll do my best to help!
