This is also with an examiner instead of my regular instructor.
What's the point of that? Sounds like a money making wheeze. If the "examiner" is concerned you're not up to snuff, he needs to sort that out with his instructors, not charge you to sit in the plane with you.
And if they do that for everyone, then either they have no confidence in their entire instructing staff, or they're out to make a few more quid from a student who doesn't know any better.
