Brand new Old Brightonian Izzy Meikle-Small, star of television series The 7.39 and the film Never Let Me Go who has starred alongside Olivia Coleman and Kristen Stewart, said picking up her A-level results was more stressful than appearing in premieres of her films.
The 18-year-old, who achieved three A* grade A-levels in English literature, government and politics and photography, said the task of studying while filming had been ''tricky'' and she is now planning to take a gap year to concentrate on her acting.
Miss Meikle-Small, who is a student at independent Brighton College said: ''I was so nervous, I didn't sleep at all last night but now I'm really happy.
''I get quite nervous at premieres and when auditioning although when I am on set I do not tend to be nervous but this is the most nervous I have ever been.''
She added: ''It's been really, really tricky, a bit of a juggling act, I missed the first half of the first term I have been really behind so I had to catch up which has been really stressful but I managed to do it.
''I'm having a gap year now to try to concentrate on my acting and not have to juggle so much. I might go to university depending on how everything goes.''
In 2011 Miss Meikle-Small became a television star when she appeared as the young Estella in Great Expectations, with Gillian Anderson playing her mother Miss Havisham.
Miss Meikle-Small, from Hove, was both a school and house prefect in her final year, and has been described as ''a model pupil'' throughout her time at Brighton College, ''known for taking part in everything, being kind to others and generally being utterly charming''.
Her most recent film roles include Disco, Snow White And The Huntsman, and Private Peaceful. Her most recent film is Pudsey, The Movie.
Her television roles have included this year's hit The 7.39 in which she starred alongside Olivia Colman and David Morrissey, as well as the BBC production of Great Expectations in which she played the young Estelle.
Miss Meikle-Small also gained nine A* grades and an A in her GCSEs two years ago.
Richard Cairns, Head Master, said: ''It is remarkable that Izzy has been able to juggle her acting commitments and academic studies so brilliantly and with so little fuss. She is an example to all of us.''
