The Yateley Comprehensive GCSE student said: 'It doesn't feel like it's really happened, I'm still getting my head around it! I couldn't believe it when they announced my name as I had tonsillitis during the few days leading up to the final. I didn't think I had any chance of winning, I was so surprised!'
