I want to book my theory test, how do i do that? Also, is there any preparation material you can reccommend?

Hi,
You can book your theory test online, on telephone and I even heard it through post also. You just need to call the DSA or go on their website.
As for material, lots of books / CDs are available in the market. You can choose whatever suits you. Just make sure they are updated and have official DSA questions.
