I see that grade allocation has now joined general election polling and the COVID virus as a topic where people can get long, technical sounding, but factually wrong, threads widely shared.

There& #39;s a 123 likes for a tweet where somebody claims to be reading Ofqual& #39;s technical guidance, yet they are apparently under the impression that GCSEs still use letters rather than names as grades.

875 likes for the start of a thread claiming that if the historical pattern includes 0.2% Us (i.e. 1 in 500) and 99.8% A*-B, then a class of 20 will get at least one U grade.

What?

Also over 800 RTs for it, many with comments saying things like "it& #39;s a scandal".

Yes, it would be. But why would you actually believe it?

I mean, I& #39;m not going through the technical manual doing the calculations, but neither has the writer of the thread.
