If you have decided to book your Full licence and the time is getting closer.. Don't think it is stupid getting a professional driving lesson/assessment prior to your test. This is the best thing you could possibly do.
Have you ever tried to play sport and at the same time verbalise what you are doing? Not so easy. This is what happens on your full licence practical test.
Everything has a process. This is the same as searching while you are driving. Drivers are more likely to continue to search if it is made easy and into a process. Knowing where and when to look is the key.
