I'm young! Same age as yourself. I got my License through the door on my 17th birthday. I did my skills test when I was 16, 2 weeks prior to my 17th birthday.
Got my IMC, multi/night to come. 130hrs. Last August I flew single handidly to Sabadell via some French airfields (Visit ANDERNOS if you ever get the chance! Great airfield nice and slack staff
). Also flown to Bern (Belp), Switzerland...my most favorite airfield EVER!
Currently doing Mod 1 ATPL's witih Bristol, due to take exams early April.
Don't worry about your skills test, be confident and most of all ENJOY it! Seriously, it cheers up the examiner too! The thing that most people do forget tho is remember to keep your eyes 90% of the time OUTSIDE the cockpit!
