Jessica Law, 19, from Warfield, was among those from the South East who went to St James's Palace in London to receive a certificate for the prestigious award, which involved carrying out voluntary work and doing a four-day expedition.
Miss Law did the first Bronze award through her school, Ranelagh, then did the Silver and Gold parts with Bracknell Forest Council. She said: "It was really amazing. Prince Edward talked to me quite a lot because quite a lot of the young people there all did the award with private schools but because I did it with Bracknell Forest Council, he took a bit more interest in it."
Of the DofE experience, she said: "I got to make loads of friends and I've discovered skills that I never knew I had. Now I volunteer for the charity and I really enjoy it so I get to keep up the knowledge I have and pass it on to others."
Miss Law, who studies bio-medical science at Brighton University, received her certificate on Tuesday last week.
