It is anticipated that a significant proportion of the cohort will continue their studies in the Sixth Form at Thomas Clarkson Academy, that has just had its best ever A Level results and secured good university places for students, including Russell Group universities.
For the first time, on Thursday, students will receive their results for these subjects in grades 9 (the highest) to 1 (the lowest).
Head teacher, Andrew Taylor, said: "As with all other schools, we were very uncertain about the implications of the GCSE reforms this year".
Maddie Porter achieved the top grade possible in every subject - grade 9 in Maths, in English Language and in English Literature, seven A*s and a Distinction*.
"Doing the exams was a bit intense but I'm happy with the results".
Pupils will be able to pick up their grades from 09:00 BST and many will go to their schools to do so.
UAH principal Steve Baragwanath praised pupils and staff for their hard work, which - together with support from parents - had paved the way for another set of outstanding results.
School performance tables will reflect schools' results in English and maths at grade 5s - considered a "strong" pass by the government.
Julia Tebbutt with her GCSE results
Nationally, around a tenth of students achieve the English Baccalaureate.
At Mildenhall Academy, 55 per cent of students sitting GCSEs achieved a grade 4-9 in English and mathematics and 56 per cent achieved at least one A/A* grade. It is a lot better than what I was expecting.
Therefore both a 4 and 5 will equate to a C grade, a standard pass or a pass not quite a B grade and the bottom of grade 7 is aligned with the bottom of grade A.
She said: "I'm very pleased".
It is expected that the same number of students will achieve a grade 7 and above compared with the old A and A* grades, with the same applying for a grade 1 and a G.
Top achievers included Simon Williams who gained 13 GCSEs at A* or A, including A* in English language, literature, mathematics, biology, chemistry, physics, history, geology, and French.
In the reformed subjects, 15.2 per cent of students achieved a coveted "9".
