The most difficult theory test questions


Skip to the test ↓

Because so many people use our site to test their knowledge, we have a rich history of data on each test question (over 1,000 questions from the DVSA revision question bank). This means we can see which questions people struggle with and which ones they find easy.

We've analysed the data from the last 100,000 quiz attempts on this site. We've then looked at the percentage of people that got each question correct. This has revealed the most difficult theory test questions.

Based on this research, we've collated two of the most difficult questions from each of the 14 practice tests in our highway code study series to produce this very difficult mock theory test.
