This book contains vocab organised into the typical topics you might encounter in an A-level exam, such as pollution, crime, etc. It not only lists single words, but also expressions for each topic.
In the back it contains several pages of phrases helpful when writing essays (i.e. on the other hand, some people believe etc.)
It also has a list of colloquial phrases to make your Spanish stand out! This book really helped me in my exams - I wouldn't say it's any good for the ordinary tourist.
