Results around the region remained steady as the first students to take new, tougher A-level exams celebrated their achievements.
Almost three quarters, 73pc, of grades in Norfolk were A* to Cs, a slight dip on last year's 74pc, while in Suffolk the figure rose from 76pc to 77pc.
While they are minor changes, they will be viewed as significant by education leaders, with many fearful that the tougher exams would put a dent in results.

In 2015, changes were made to move A-levels away from coursework and instead only have exams at the end of the two-year courses.
A handful of schools celebrated record results, including Wymondham College and Sir John Leman High School in Beccles, while others saw disappointing drops, including Thetford Academy, which fell from 71pc of A* to C grades to 59pc.
At Diss High School, Dr Jan Hunt, headteacher, celebrated the school's 79pc of C and above grades with proud students.
But she said the success came after challenging preparation for the new system.
'They are stunning results,' she said. 'We are very happy indeed. Despite the increased challenge in content of the reformed A-levels, students have worked hard and achieved to the best of their ability.

'It has been a challenge for staff to prepare students thoroughly for more challenging A-levels and they have risen to the occasion very well.'
Stuart Dark, vice-chairman of Norfolk County Council's children's services committee, said: 'Today is a fantastic day to celebrate the hard work of students, staff and families across Norfolk.
'To students, remember that today offers every one of you a fresh start – whether you achieved better than you expected or not quite as well as you'd hoped.'
Another success story was Springwood High School, in King's Lynn, which increased its level of A* to Cs by 9pc, a difference headteacher Andy Johnson described as 'absolutely fantastic'.
By 12.30pm, the University of East Anglia said they had received more than 5,000 calls from students hoping to secure a spot on one of their courses through the Clearing scheme.
