In South Africa some universities have introduced cameras into exam halls, but cheating is probably rampant at those that haven't. I've been in an exam where people in the next row (teachers no less, doing what seemed like an easy exam) were blatantly cheating. First world notions of "honour" and "integrity" don't gel well with third world aspirations.

Oh and South African Indian students (in the country for generations, and affluent relative to the rest of the population) are amongst the biggest cheats. A BCom (commerce) degree held by an Indian graduate from the the University of KwaZulu-Natal (UKZN) is something to be viewed with great suspicion.
