A major overhaul of the GCSE system in Wales has been introduced.
It'll mean pupils studying a different qualification in Maths, English and Welsh to their counterparts in England.
They'll start learning a second GCSE in Maths - focusing on numeracy - while the English and Welsh exams will have a bigger emphasis on reading, writing and listening.
There'll also be changes to the Welsh Baccalaureate and AS and A Levels.
Watch the report from Mike Griffiths below:
Radyr Comprehensive School is one of the schools who've been involved in shaping the new qualifications.
We asked Year 10 pupils what they made of the sample questions they've seen so far...
The Welsh Conservatives haven't greeted the changes so warmly, arguing the qualifications will "lack credibility" outside Wales.
There've been words of scepticism too from the Association of Teachers and Lecturers.
The Welsh Government insists the new GCSEs are the product of years of consultation with schools and employers.
As for how well the exams themselves perform, we won't start to get a real sense of that until 2017.
