Bad grammars

"What are they thinking of?" fumes Stephen Pollard in the Mail. "No one can deny that our state education system today is shamefully bad ... One small area, however, manages to do well. Very well. 98.5% of grammar school pupils get five good GCSEs at A to C grades, compared with the overall rate of 58%. So what's the marvellous notion that David Cameron's Conservatives have come up with? Ditch any remaining attachment to the one proven, successful type of state school that's left."
