It makes good sense to start working on your theory aspect as soon as possible to begin to identify road signs and markings etc.
The theory test consists of two parts, the first consists of multiple choice questions and the second tests your hazard perception skills.
There are 50 questions in the multiple choice section and you will need to get at least 43 of these correct. I can help you with your preparation for this test.
The hazard perception section shows a number of video clips simulated as if you were driving the car, and you have to click a computer mouse as soon as you see a potential hazard developing.
