Revised for about two days before the exam, about four hours a day or something. Passed first time, used a RAC test book (with answers) and the highway code to revise the theory and a CD to practice hazard perception.
i found it quite easy. i studied for about a year, but not properly until about 3 months before, would do a bit each week but nothing major, until 3 months before where i was studying for at least half an hour a day, used to do the disk while watching tv so i could study for ages but it wasnt a case of looking at a screen or the book for hours on end.
i tried the book but was so long and boring i bought a cd rom instead and used
"Driving Test Success ALL Tests 2009/2010 Edition (PC)" which was £5 at tesco and found it really good to get along with, when doing practice tests it tells you why an answer is wrong before it lets you move onto next question so it sinks in better.
i passed first time and made a booklet of things i was struggling with and spent an hour before the test memorising themm only for them not to appear on the test. i got 48/50 on theory and 57/75 on hazard perception so disk cant be that bad.
8/10, I started revising the day before, passed with flying colours. I skimmed through the book, and just kept going on the CD test until I was passing frequently. Hazard perception is easy too, if you have any sort of road sense then it will be a breeze.
8/10. I used a CD and did like 100 questions from a book. Plus flicking through the Highway code sometimes. It wasn't as hard as I thought and doesn't take as long as you think. I think mine took about 25 minutes and you get an hour or something.
Just make sure you read the question incase you make a silly mistake. Plus if you take too long on the multiple choice you could get bored and then you have hazard perception and you're tired and you could react slowly.
I did it about 4 years ago and then never did my test with uni and whatnot and it expired so I had to take it again. First time I swotted up on loads of things, second time I read the Highway Code book once the day before. Passed both times, had a lower score the second time ofc. Most of it is common sense aside from fact questions like tire tread depth which you just memorise. Good luck.
It's pretty straightforward even if you haven't revised at all, I'd say. I put in about a week's revision using a friend's theory test CD and managed to pass it first time - I'd very much recommend you use the same technique. It takes a little while to get used to how the hazard perception test works, but actually having a simulator to hand makes it very easy to understand.
