More than 30,000 students across Wales are waiting to receive their GCSE results.
For many young people the focus will be on their GCSE English language results, after thousands received shock low grades in their January exams - more than 90% who sat the units in January entered to re-sit them this summer.
An ITV News investigation also found that there were divisions between the exam regulator, the Welsh Government and the exam board WJEC when the new GCSE was accredited in 2012.
The new English language GCSE, especially for pupils in Wales, was created after papers were regraded in 2012.
But there are warnings today that some pupils will suffer after January's results.
The Welsh Government and WJEC both produced reports looking into what went wrong, with no clear answer. They have both pledged that this year's pupils will not be disadvantaged, compared to previous years.
