no...
Jenn,
No, actual scores mean nothing. There is no GPA listed once you receive your certificate. It's pass/fail just as MC replied. And no, employer's don't care on test results. It has always been said, at least on our side of the pond, that an A&P certificate was a "license" to learn. The best investment you can make is after you are hired, work hard and volunteer for anything...and see if there is an ancient mechanic around that will impart their wisdom to you...be sure to take notes!
Good luck.
