Well I have 3 degrees, including a masters.
I passed all the ATPLs first time, but on my CPL I forgot to push everything fully forward on my asymmetric GA so I got a partial.
That was really really stupid.
As someone really clever once said "there is no-one so ignorant as an educated man."
Yes I still do kick myself, and with my IR coming up I wonder what the chances of me doing the same thing again are?
To pass the ATPLs "Dedication is what you need" and luck, and good feedback.
