Flo, who lives near Ilminster, received a brooch and a certificate to mark her achievement, which took eighteen months to complete.
As part of the process Flo enrolled as an Air Cadet, played for Chard Ladies Hockey 1st team and passed her Grade 8 Flute exam.
The expedition, which is the final part of the qualification, took place in the Brecon Beacons.
Flo described the experience as, “Hard work, requiring a lot of determination but it was also very enjoyable”.
