My dad knew and he sorta showed me at his shop, or one of his
moonlighting part-timers did (he had a couple of guys who were senior
techs at Sikorsky). I didn't say I had the knowledge of a trained
electronics tech, but I am sure I could have learned if I wanted to do
so. I did "ace" physics, calc, and chem in high school, and these were
all AP courses taught in small classes by first-rate, no-nonsense
teachers.
I'm sure you had first rate teachers. Problem is you were a 3rd rate
learner.
No, stupid...you had to take tests to get into the AP classes. You, on
the other hand, seemingly did not have what it took to get into an open
admission community college.
