Our expert says:
This is unfortunate and many young people who can drive under normal circumstances fail their tests because of nerves. The sugar could have the opposite effect as too much sugar can make people quite edgy and more anxious. If possible I would suggest your daughter seeing the family doctor or a psychiatrist as there are some medications that can help calm nerves for one-off type situations. It is also about mindset going into the test and your daughter needs to be encouraged to think to herself going into it that she can drive. Telling herself this can provide self-belief - don't worry about making mistakes, but rather show the examiner what you can do rather than worrying about what you might not get right. Also lots of practice helps improve confidence, so she should drive at every opportunity within the boundaries of a learner licence.
