Welsh students 'may be disadvantaged'published at 09:09 British Summer Time 13 August 2020
In Wales, students have been assured they will not get lower grades than their AS-level results.
Anna Brychan, of University of Wales, Trinity St Davids, warned Welsh students may be disadvantaged as the system in England - where grades cannot be lower than mock results - is different.
"Your students could be marked down because of [the school's] historic results and that feels, and is, deeply unfair," she says.
"In the appeals process, if we can look at prioritising or giving a voice to those schools in that position, that would be a very valuable thing to do."
