The exams and CQB are in a dreadful state, and require a major overhaul. They certainly need to be made more relevant. But in my opinion any overhaul should actually make them much more difficult to pass.
At the moment we have lots of people passing exams by memorizing answers, then rushing off to spend vast sums of money doing very expensive flight training. Many of them then find it impossible to get jobs as pilots and they and their parents are stuck with large loans to repay.
If the exams were much more difficult, many of these people would drop out of training before spending (wasting) any really serious money. This would of course be very unpopular, but this is a situation in which it is necessary to be cruel to be kind.
