Blog post on twitter yesterday showed the difference in grade boundaries for (I think) English over the last few years. Steadily more difficult to get A*, A, B & C grades as boundaries were moved up but D & E grade boundaries have gone down - so frustrating that it isn't even consistent.
This year if fewer students get the higher grades it will be because Gove contined to raise standards and make exams more rigorous. And as a consequence of his meddling, teachers will be put onto competency procedures, students will miss out on 6th form & college places and parents will lose faith in the system even more. It's utterly shambolic.
