I started flying in 1963 as an Air Scout on gliding courses and achieved my dream of sponsorship for my CPL/IR in 1966 starting my training at the tender age of 19 yrs. I had a few O-levels.
I got a Masters degree in 2001 aged 53 yrs, unrelated to aviation, by distant learning.
You don't need a degree to go flying just live the dream and have lots of fun.
