Interesting Fact - School in the UK

The average size of class in a state school in the UK is 21.

(The average public school (that's the one you pay for) classroom contains 10 pupils.

The maximum size used to be 30, but the UK government recently relaxed rules so that class sizes can now be 31 or more, due to a rise in demand for places.

I taught a class of 31 adults once. That was fun.)
