The content sits inside the game
A mission that feels like a test stops working the moment it is recognised. So the material sits inside a riddle, inside a code to crack, or inside a point that has to be found, and the student meets it while already inside the game.
Multiple choice, a written answer, a numeric answer or a photo. Each is checked against the server, so nobody ends the day with forty exercise books to mark.
Works in the room and works outside it
An end of lesson activity can run inside the classroom itself, with no map and without going anywhere. An activity day, a year group trip or a campus tour runs on the same system with real stops.
You watch one screen with every group on it. Who has moved on, who is stuck, and who answered what. At the end there is a full report of the answers, and it exports to a spreadsheet.
