Educator Copilot creates classes

What changed

• Educator Copilot can now create a class and give an assignment to one of your classes. Its welcome screen lists what it can build.
• Older assignments no longer crash the scoreboard. A worse late resubmission no longer marks an on-time grade late, and a grade override no longer wipes a submission saved at the same moment.
• Cloning a quiz keeps its AI setting. Students on one campus network no longer block each other's whiteboard drawings.
