There are a variety of factors that can influence how well or how fast you learn to drive. These might include the amount of hours you put in behind the wheel, whether you are having private lessons as well as lessons with a driving instructor, and your overall attitude to driving as a whole.
One major factor however is your driving instructor. Many would say that the qualities a good driving instructor needs are to be patient and calm, but also to trust you when you are driving. They should also always be punctual for your lessons and reliable, and should be honest with you at all times, to make sure you get the best out of their service.
Safe driving from Britannia!
