He notched up A*s in biology and chemistry, As in English language, maths and physics and Bs in geography, English literature, religious studies and Spanish.
He said: “I am very pleased with my results. They are slightly better than what I expected.”
Lewis is going on to sixth form to do biology, physics, chemistry and maths.

“I’m just so happy. I’m over the moon,” he said. “I did not get any sleep the night before.”
Beer will now study art, photography and media in sixth form.
