I agree with the idea of "mock" exams. In one of my roles I swap hats and work as an LPE examiner for a JAA CAA. The exam board we use make the format of their available on their website in addition to offering a "pre-test" which has a slightly different format. Generally there are the pilots who enter my exam room having done their homework, listened to example tests, taken a pre-test and having spent as much time as possible before the test communicating in English and there are those who are not so proactive. Of these general pilots it is the former that tend to sail through the exam coming out with a Level 5 where they thought they were only in line for Level 3. Now could that be just a little more than coincidence?
