There are entrepeneurs who are uni graduates (Buffet, Carlos Slim); some of the others who famously did not finish uni were perhaps too smart for the tertiary education system (Gates, Jobs).This thread seems to be going the same way as the truck driver thread.
I do find it interesting to note the vast amount of entrepreneurs who were high school drop outs. The school system is an invention of the industrial revolution and as such is (in it's very design) geared towards creating worker drones.
ENTER (or TER) scores are worth very little once you turn 21 (mature age entry).
But there are also many who didn't do at all well at school.
TER is perhaps a good indicator for the majority who follow a mainstream white collar job. It provides an indicator of one particular sort of ability. There are many other sorts of ability, some of which can lead to very fulfilling careers.
