You might think I was a relative sprog, being on APC 318, but I was a "mature" student at the top end of the range when I went through. Not saying it was harder being closer to 30 than 20, but I was on review that many times I nearly had enough hours for ATPL(H) when I finished! Needless to say, after the course I was able to prove old age and treachery will always beat youth and exuberance.
