Systems and flying are the easy part of the job. Granted, knowbody likes being tested in training. The difficult part is applying the knowledge out on the line. Like a previous poster said, "Cooperate and graduate," and THIS will give you a good foundation for learning how to operate on "the line." An airplane is an airplane. You won't be building them. Red is bad, green is good. 175 or 145 both are excellent designs that are forgiving and created for the 250 hour pilot wonders of years past.
