It's irrelevant to the test. The examiner will say" Sorry to hear that, but I'm here to see if you can can actually drive, shall we get started on the test?"
Stop trying to BS your way though life, people see through that pretty soon. If you want a drivers licence, study the driving manual, practice your driving, and pass the test. If you know how to drive there is no need to be nervous, and examiners pick up on that as a sign you aren't ready to be driving. They want you calm and competent, (not over cocky) so it looks like you know what you are doing.
