>The consumer version of Guided Learning is already available within Gemini, and can enable cheating. In a reporter’s test, it produced a detailed essay in response to an Advanced Placement history prompt.

I don't envy trying to stop cheating in an AI world, but when a student gets to the AP History level, if they want to cheat they'll know how to do it, with or without using a Google product with their school login.

Best you can do is guide them down the "correct" path, which itself is going to be harder and harder with AI generated content out in the wild.
