I was in the same boat last year when I did my test and passed on my second. All you need to do is believe yourself, say to yourself that you can do it. Just remember things that you did wrong on the last test and avoid doing that again. Try not to panic as if you panic you are more likely to cause an accident. One thing that worked for me was that I wasn’t treating the examiner as a examiner, I treated him like a friend or family that was in the car as last time I panicked about the examiner all the time. If you think they are family you are more likely to considerate on your driving as you don’t want to harm them.
