Pupils collect GCSE results in Wales
More than 600,000 teenagers in England, Wales and Northern Ireland are receiving their GCSE results, with head teachers saying changes have caused "a lot of turbulence" in grades.
From next summer in England all pupils will sit exams at the end of their two-year courses but in Wales there will be no changes.
The BBC's Hywel Griffith spoke to students collecting their results at Rhydywaun school in Wales, who told him re-sitting exams did help.
