'Star' Burgess Hill Girls student Selina Wang achieved grade 9 results in nine GCSE subjects
Her amazing achievement comes as a study published by Cambridge Assessment in May, predicated that only 200 'star pupils' in the country would get straight grade 9s, the school said.
Headteacher Liz Laybourn said: "We believe in challenging each individual to be ambitious and achieve the highest grades of which they are capable.
"Teachers work hard, going above and beyond, to ensure that girls meet these high standards and reach their full potential.
"Yet again, this year’s results prove that the Burgess Hill Girls experience adds significant value to each and every girl.
"Not only have they achieved superb grades across a wide range of subjects, the girls have also taken full advantage of the amazing opportunities that the school provides on the sporting, creative and enterprise fronts.”
A further eight students achieved 100 per cent grades 9-7 (A*/A): Isabelle Flower, Olivia Gunn, Olivia Player, Charlotte Hinton, Niamh McNeill, Emma Naunton, Cathy Tong and Rose Wainner.
