I was loaned a CD (or it may have been DVD) which I think was an official one. What I discovered was that if you did all the example questions on it, you had covered every one that they might use in the actual test. I had full marks in the theory part because I had been through the CD loads of times, and when I sat the test I had already seen all of the questions and so knew all the answers.
I’ll try and find out what it was - it certainly did the trick for me. Shame they don’t do the same for the class 1 driving
