Nicola Sturgeon apologises for getting the exam results wrong.

The Scottish exam Authority looked at the results that had been marked by the teachers and downgraded 15% from deprived areas and 6% from affluent areas, but how can this be so? Surely the Authority simply has a name on the paper, not their home address, sure there could be no bias in their review, maybe the bias was originally in the teachers marking that upgraded the children’s marks from the most deprived areas?
