[TowerTalk] Dumbing down?

[Peter Chadwick]

I have seen answers to the Extra Class that are just plain wrong. No ifs, ands or buts.
That can be the trouble with a multiple choice exam, unless the people setting it really know their stuff................But a recent proposal from some teachers in the UK is that no-one should be said to fail anything - just to have achieved 'deferred success'. Because if kids 'fail', it discourages them. Words fail me............

And some think the extra class license is still too tough.
