GCSEs: WJEC's fears for re-grading repeat
An exams body has raised concerns that the situation which led to the re-grading of more than 2,000 English language GCSE papers in Wales last year could arise again.
Following accusations the exams had been marked too harshly, affected pupils secured a higher grade in 2012.
The Welsh government branded the WJEC's comments "silly" and insisted there would not be a repetition.
The High Court ruled against a bid to overturn English GCSE results.
