Barking is a large place in London that has high congestion and traffic flow. When learning to drive, you may encounter many challenges early on as there are more drivers to look out for. Barking itself has a population of 200,000+ which is a very large number. Barking is also connected to major road networks such as N Circular Rd and the A13.
Sometimes you may drive outside of Barking to get a mixed driving experience of the nearby areas such as Stratford, Ilford, Dagenham, Woolwich and Goodmayes.
Nearer the latter stages of your course, your instructor will reserve the last few hours of your course to the city your test is based in. In most cases, Barking will be the main test centre of choice.
