Since the AA Driving School launched its theory test app, its users have taken more than 33,000 mock tests and passed more than 17,000.

The analysis comes as new AA/Yonder research** reveals just 18% of drivers are totally confident they would pass their theory test if they had to re-take it.

Young drivers were twice as likely as older drivers (aged 65+) to be extremely confident they would pass a theory test retake (33% vs 16%).

Male drivers were almost twice as confident as female (21% vs 12%) in their ability to pass a retake. Current DVSA data*** shows the pass rate for the theory test is 47.2% for female and 43.7% for male candidates. 

In 2023/24 the pass rate for the theory test was just 45.2%.

Camilla Benitz, Managing Director AA Driving School, said: “It’s fascinating to see which theory test questions people find the hardest to get right on our app, and hopefully the list will help people revise successfully for their test.

“Knowledge of driving theory is important beyond the test though. The top question pupils struggled with is about how to safely rejoin the carriageway after you have stopped in an emergency area. Clearly knowing how to do this correctly is key for your safety as a driver.

“Qualified drivers, many of whom are not confident they have enough knowledge to pass a retake of the theory test, may want to brush up on the Highway Code to ensure they have the information they need to drive safely and correctly.”

The AA Driving School Theory App launched in October 2023. It contains more than 700 theory questions and extensive hazard perception clips. Learners can use the flash-card feature for quick-fire revision sessions, access content when offline, take timed mock tests and track their progress.
