Unless something has changed in the last three years there's no such exception for foreiners.
If a foreiner wanted an easier theory exam for a comm that wasn't to be used in SA or on ZS registered aircraft there would be no need to train in SA at all. I did the SA comm and didn't think it was all that difficult but did include lots of irrevelant crap just like Europe.
The US and Canada have got their ducks in a row and safety records to back it up. I am European by the way.
