Yep. Thus exam is big stuff. I recently had a ZA educator as a resume client. One of her brags was the number of students she prepared for successful exams.
The education story, in RSA, is something that few people outside of that nation now anything about and going back to the Soweto Riots of '76 ( which was about blacks being encouraged by the stinking COMMIE ANC ), which, in its way, caused the WEST to start condemning the whites there.
In '76, they whole very idiotic DEMAND that blacks be taught in their own tribal languages, instead of English or Afrikaans, when there were not enough QUALIFIED black teachers who spoke all of the different black tribal languages was crazy!
First of all, not being able to understand or speak the two major languages that business was/is done in there and especially English, which is used world wide, kept/keeps those who can't/don't speak them down.
Secondly, insisting on having UNQUALIFIED teachers, solely because they are 1) black 2) can speak a relatively unusable language 3) self segregating and then complaining about all of those things being what's keeping blacks "downtrodden", is sheer INSANITY!
