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...
There's a lot more problem solving than I thought and a lot of writing.
They enjoy doing real life problems that they relate to in Mathematics and I think if there's a focus in what happens after school through their education when they're in school, it can only be a good thing.
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.
I don't think anybody would dispute that Maths, English and so on are the key qualifications that any child will get.
The Welsh Government insists the new GCSEs are the product of years of consultation with schools and employers.
We've also worked with colleagues within and without Wales.
As for how well the exams themselves perform, we won't start to get a real sense of that until 2017.
