I believe there is also an app that you can install on your phone (Android and Apple) provided by the R&A, its the Rules of Golf, very useful to have and to find out information quickly.
There is also a RandA book that has pictures in, which I found immensely helpful rather than just reading lots of text. My felt tips ran out, after chapter 4 though.
They also have an online academy that cost £10 to take the test, which was interesting, but better to read the rules in pictures book first.
