Wow this is a convoluted system. It took us over an hour to get into the exam and required at least 30 mins to tech support to get it all running.
Is it known to be difficult? I'm fairly tech savvy and even watched the insanely boring videos (where's a nice paper manual with an index when you need it) but I couldn't fathom what we were doing wrong.
Turned out to be a glitch that the system didn't recognise that we had closed down all applications. It took a long time to figure out.
It shouldn't be so hard.
