We are looking online for the life in the UK practice book. There is an option to buy the books, or to sign up for a course. The course is 3,6,9 & 12 months. I have no idea which would be better. Practicing on his phone or laptop would work better for my husband rather than having the books. Should he sign up for the course? Or alternatively he can download the book as an e book but there would be no way of filling in the questions online. An app would be great to practice on but it doesn’t seem to offer one. What do you guys think is best?
