Firstly I would like to point out that I have not read this guide. But I have just sat my A2 General Studies Paper and I would like to point out that it was the easiest exam ever! One of the questions was "What does anti-semitic mean?" And it was based on a comprehension so the answer was obvious (I would like to point out if you don't know the answer to the question you better get the book... In fact don't get it your going to fail anyway, let's face it). Our teacher, well not really teacher because there is nothing to teach for this exam, told us there was nothing to revise, he was right, if you don't have general knowledge of how the world works by now then you have no hope. So save your time and your money, and good luck!
