The overall pass rate of students receiving A* to E grades was down 0.2 to 97.9 per cent, however this is in line with the national figure.
There were individual success stories being reported across schools and colleges in the state and independent sector yesterday.
Among the top performing students in the region was Harriet Matthews at Mount School, in York, who achieved four A*s and an A and will read Geography at Edinburgh.

A “genius” 14-year-old has added to his already-impressive CV after sitting his A-levels four years early.

He gained an A in computer science and C in additional further maths.
