← Caso Abierto for the classroom

Check an SQL arcade certificate

Check that the code a student handed in matches their name, the worlds they completed and the date.

What you type here isn't sent anywhere.

What it's for and what it isn't: the code stops students copying a classmate's, because it depends on the name. It can't be made forgery-proof, since it's calculated in the browser with no accounts or server. For a class activity that's enough; for an important grade, it's better to watch the student play.
