There were a good 10 questions that were ambiguous a couple that were just wrong: (50 psi is a PRESSURE not a FORCE, and at least two of the pulley questions had ropes coming out at significant angles from the bottom pulley which changes the advantage).
Still I've had enough practice at figuring out what people MEANT to ask to get 98%. Missed half of the same 4 part gearing question everyone else did. You just had to have learned the nomenclature somewhere (assuming they're not just wrong).
And yet I can't get my motorcycle running...
