When studying for a driving theory test, the Highway Code and other car driving books should be read. The theory apps can be complemented by using other driver training aids. Focusing on the test only has limited learning value.
When studying for a driving theory test, most learner drivers use the available apps and Practice theory test for car drivers. Which is OK to get used to the technique required for the theory test itself. This method of learning the rules of driving is limiting your knowledge to what shows up on the app or sample test paper.
Why not just use the apps?
The apps. available and sample test papers will not have all of the real questions that will turn up on the actual theory test for obvious reasons. Studying for your theory test using this method does not 100%prepare you for the practicalities of driving on the road. Neither does it prepare you for your driving test.
Your confidence in driving a car will greatly increase once you know more rules of the road, rather than focusing on a driving theory test. Lack of confidence comes from a lack of practice and knowledge. As an example, would you attempt to play a game of football without first knowing the rules? So why then would you drive a car, which is a lot more dangerous than playing a game of football?
Best way to gain extra knowledge
The best way to gain this extra knowledge for a driving theory test would be to look at the latest edition of the Highway Code, which you can do here. Additionally, you would need to find a DVSA Approved Driving Instructor (ADI) who can help you interpret some of the driving rules you are not sure about. I was teaching the doctor to drive who wanted to be dropped off at home instead of the hospital to demonstrate the point. I wasn’t familiar with the location, so I suggested that the pupil could drive themselves. So long as I was told which turn was going to be taken in advance.
After a while, the pupil said they were going to turn right soon after passing this sign. Immediately after passing this sign, the pupil signalled right and started to move into the section of the road reserved for traffic to enter the road we were on. I said to the pupil. “What does that sign mean?” The reply came back. “No, U-turns,” I replied. “What do no U-turns mean?”, “I don’t know.” Was the response. The pupil knew what the sign stood for, but not its actual meaning. This means the theory test would have been passed, but not a driving test.
