Thanks. I've been ripping though the CAE maths and physics at work and I've been scoring well first time on the tests. I've got a few more quiet nights ahead in which I can revise in peace and quiet.
I'm most worried about the CAE version of the "Advanced Flight Simulator" . I feel like I'm just best guessing within the 4 second window , I'm still better than average but that isn't instilling much confidence.
