Well, I had to take the commercial test (CDL, not aircraft) 6 times
before I passed it (pre-trip), twice on the manuvers and twice on the
road test.

For those of you who want to try this (for class A), the trick to the
pre-trip is you are teaching them to do it, not doing it yourself. They
only want to know that you know what and where to check in what order
(for air brakes).

For someone with an instrument rating, having passed all my aviation
stuff on the first try, *this* was really embarrassing.
