The change fits with the "no winners or losers" philosophy.I'm pretty sure that when I last took exams (GCEs in 1976) the pass/grade boundaries were 'adjusted' to ensure a constant percentage got each grade. This seemed sensible to me as employers etc could tell you were in the top 10% or whatever at a certain subject.
But I notice that each year now, they talk about the percentage of A*/A etc going up and down (highest ever etc). Is my memory playing up, or did they change the way grade boundaries were defined sometime over the last 50 years ?
