Tiny Jake Frood, who stands at just over 3ft tall, has astounded his instructors after achieving the accolade – unheard of in someone so young – despite suffering with juvenile arthritis. The four-hour exam was gruelling for Jake, as he was on strong pain killers to battle through his condition and severe hypermobility disorder to reach his amazing goal.
