Thanks brother.... There is absolutely nothing to get on nerves. Develop the sense of being a sensible driver who not only protects himself but who protects others also if they are not driving properly. Just follow the traffic rules in daily life as well & be sure that you are a much better & sensible driver than most out there on the roads. This confidence will be more than enough to pass the driving test.
But you know some people have exam phobia. I have a colleague in my office who is a very good driver but he failed for 3 times & is now preparing again....
What could be the worse???? Max could be that you fail the test.... So what? Will they put you in Jail? No... Only that you have to retake the test & meanwhile you can continue driving as a learner. That's it. Goodluck
