What's in the files they've already released? Some of them are > 800GB.

Where are you getting that information from?

I'm under the impression files are getting released 12th May. I don't see any reporting on 800GB?

Grades, records, etc I would assume. Someone else pointed out that they recently acquired https://www.parchment.com/ so they may have also been able to scoop up those records too

I'm guessing loads of student work? If so, it'll be great for anyone who wants to research AI usage in papers.
