Failure
There is no limit to the number of times you can attempt the theory test. Having said that, each time you fail the theory test twice for category B, you will be required to attend a minimum of 12 hours of theory lessons via an accredited driving school. When you come to the centre, you will need to bring a course certificate proving that you have attended these hours of lessons.
You cannot attempt to pass the theory test again on the same day that you fail.
