GCSEs: 'Two years solid work' at Ysgol Friars, Bangor
The GCSE A* to C pass rate has stayed at 66.6% in Wales for the third year running.
But Welsh results are now the same as England as a whole and better than most of its regions.
Top A* and A passes were up slightly (0.2%) to 19.4% and better than northern and midland English regions.
Education Secretary Kirsty Williams said it was "another strong performance".
Pupils at Ysgol Friars in Bangor, Gwynedd, gave their reaction, while head teacher Neil Foden said it was not about cramming but solid work over two years.
