The rim your probably right, but the worrying thing for us mech's is that 90% of the sparkies at the SIT hold there mech basics, just a few basic worksheets and they are B1, and the other thing is the 380 course is run that the B2 guys sit in on the B1 course as well as the B2, there are numerous sparkies already holding B1 basic, not to many mech's.
