Its a must have!
This is something every learner driver must have, it is an excellent way of building and revising knowledge before your theory test. I passed first time (similar to other people who have reviewed this product), if you take the time to use this you will too. The hazard perception clips are great to practice, I even found that some of the theory questions come up in the test. You learn your mistakes, review them and can try, try and try again until you are ready for your test. Well worth the money to save repaying the theory test :)
