The PM, no, they don't. I have emailed them and expecting to hear some feedback about the answers at some point, but doubt that'll happen within the next few days.
I think some of the answers provided are purely incorrect (not bad for a $33 exam), such as Ayres Rock, 'in the vicinity' and the ramp check, but the duty time questions do interest me as it's certain those will be in the CASA exam.
