I can't see a direct saftey issue in only the CAA Holding Exams.
In the States there is compition, the ATPL cost about £50 and the results are within 30seconds on lasergrade.
I've seen Two exams where they forgot push the "Jumble" button on the computer, all the answers were A! French Annexes, incompete and unchecked questions ect. I think the argument for a lowering of standards wouldn't be applicable!
PS I got a bargan £700 set of ATPL exams!, the price was increased shortly after
