Martha, pictured right, who has been passionate about baking since she was young, was selected out of thousands who applied from across the UK. She has been juggling filming for the show over the last few months with her studies and AS exams at the Sunningdale school.
Martha, 17, who lives in Ascot, said: “I am so incredibly lucky to have had the amazing opportunity to be on the Great British Bake Off. Never in a million years did I expect to get through the auditions, let alone onto the programme! It has been the best experience of my life and I have loved every minute of it.
Andy Linton, Head of Year 12, said: “We are very proud of Martha and delighted she has been given this opportunity to showcase her skills.”
