As promised we are providing suggested answers on this website to the questions in the AS book . You will find the answers to questions from chapters 1 and 2 in the Book Resources section of this website (click on the appropriate chapter). Other answers coming soon!
In some places there are no answers – for example at the end of chapter 1 one of the suggested activities is to constuct a mind map of the chapter. We haven’t drawn one ourselves but would be pleased to see any student efforts – there might even be a small prize in it. Send you efforts to firstname.lastname@example.org
Also, do let us know if you spot any mistakes, or have any suggestions for better answers. We are always pleased to make corrections.
