KOs are hit and miss in many subject. Essentially, there is definitely knowledge you need in English but it is tested through very distinct skills : you can know all the stuff, but if you can't express them and apply them , you've had it.
In six years , people may well debunk all this but at the moment the knowledge rich leaders are crowing on Twitter.
