Your instructor will continuously assess your driving and remind you of any mistakes you may have made. This will help you to avoid those mistakes and turn your good behavior into habits.
Before your test, you can ask your instructor for a mock test. The test procedure will be exactly the same as the real test. It will start from RMS parking and finish there as well. A complete simulation of the real test will help you build confidence towards the real test and you will receive comprehensive feedback on all the mistakes you have made to avoid making them again.
