"seems to work for pilots...."
RP,
Hardly the same is it? Pilots (in the normal way of things) all learn to fly a basic aircraft then specialise. Except for amputees along the way, no-one undertakes unecessary training. They don't all learn to fly a light multi, for example, do they? To take your point, it is appropriate to stream, but it used to be done post AAITC.

Course critique! What planet are you on? I live on the one where constructive criticism is universally accepted as a good and worthwhile thing. Except by anyone getting criticised of course.
