What do I need to remember from case studies and how do I use them in my answers?

Case studies are a great way to provide evidence for an argument you want to make in a question. I would ensure that you have at least 4/5 key facts of a case study when revising - e.g. Place, Date, Event/Project, Key Players, What's the relevance? - It is always useful to have the facts of the case study but also understand how this can be used in an answer - think 'so what....?' For example - Curitiba a sustainable city - what is this an example of? How could I use that in my answers? (e.g. in development/sustainable cities/environmental sustainability/ efficiency/ LDCs)
