A Sixth Form pupil at Rydal Penrhos visited Buckingham Palace to collect her Duke of Edinburgh Gold Award last week.
Jenny Johnson joined other candidates at a ceremony on Thursday, just days before the royal wedding between Prince Harry and Meghan Markle.
She received her certificate from rugby star Johnathan Davies and met Princess Anne at the garden ceremony.
Jenny said: “It was beyond everything I was expecting and all the hard work to get my Gold Award was definitely worth it.
“I would highly recommend it now more than ever as it really is a once in a lifetime opportunity to meet royalty and gain a qualification that stays with you for the rest of your life.
“Princess Anne was really lovely and we spoke about what I had to do throughout the process to get the award, and she was really nice and kind looked beautiful.”
Jenny is the latest to take advantage of the school’s DofE course run by Dr Jim Lewis, with Jack Sissons, Will Marston and Katie Marston achieving the feat last year.
Tim Cashell, deputy head, said: “Jenny can be enormously proud of her ongoing commitment throughout the Duke of Edinburgh scheme, and her day at Buckingham Palace was richly deserved when you consider just how hard she worked to achieve the qualification.”
