there are so many avaliable and i am not sure which ones i need to pass the test

do i have to buy just the one book or all three

please advise

hi I bought the LIFE IN THE UK book and studied chapter 2,3,4,5 and 6. Also I got the multiple choice book to go with it and I did the test from this website. Make sure keep a note of the questions you get wrong and keep revising it. That's what I did and I finished in 4 minutes and to be honest it's the second test I've passed in my my life. Good luck mate
