Numbers getting top A-level grades improves in Wales
The percentage of Welsh students achieving the highest A-level grades has risen for the first time in five years, but the overall pass rate fell.
The number of pupils who gained A* grades is up from 6% in 2013 to 6.7% - the highest since the grade was introduced in 2010.
But the proportion of students achieving A* to E grades fell slightly from 97.6% to 97.5%.
Wales has also narrowed the gap with England after top marks fell there.
The number of students gaining A* and A grades has also increased from 22.9% in 2013 to 23.3% in 2014, ending four years of steady decline.
Girls continued to outperform boys in Wales, apart from at the highest A* grade.
In England, the percentage of pupils achieving A* grades is up, but the numbers for A* and As combined are down for the first time in over thirty years, narrowing the gap with Wales.
Joining students collecting results at Gower College, Swansea, Mr Lewis said: "Once again our students have done us proud."
"I was very pleased to see the progress our students are making in achieving the higher grades, particularly in key subjects such as physics, history and chemistry which all showed improved A* and A pass rates compared to last year.
"Our performance at A* to C for mathematics, chemistry and history also compares favourably with other parts of the UK and performance at English at A* to C has made great strides.
"These subjects are important for our economy and will stand students in good stead for the future."Analysis by education correspondent Arwyn Jones
For the vast majority of students it will be a time to celebrate, even if it does mean a few frantic phone calls for some to get on the course they want.
And on that front there's good news. As the higher education sector becomes more and more competitive, universities will be keen to attract students. The advice is phone them, and phone them early.
The low numbers getting the top grades in Wales has been a cause for concern for a number of years.
Today's results show that the numbers getting either As or A*s has gone up for the first time in five years, although it's still lower than two years ago.
In Wales, thousands of pupils will also be getting their Welsh Baccalaureate qualifications (WBQ).
The numbers studying for the WBQ has steadily increased over the past few years as it has been rolled out across Wales.
Currently it is a simple pass or fail, but there are concerns that some universities have been more willing than others to accept a pass as being equivalent to an A-level A grade.
However that could change as the WBQ will be graded in two-years time from an A* to a C.
