S: I've been asked to write a case study. Can you tell me what this consists of?
L: Yes, this is when you write about a real thing. And you describe it. And you recommend what to do with it. So this thing could be a business, for example. Or it could be a patient that needs treatment. Or it could be, perhaps, a tourist destination. And you write about this thing and the context in which it is taking place. And then you go on to give some recommendations about what you should do about this thing. Sometimes you write as if you were an expert. Usually the thing is a real live thing, a real business or a real patient. But sometimes, occasionally, your tutor might give you a made-up one to write about. But you treat it as if it was real.
S: Oh, thanks.
