How many quotations do I have to know for the exam and how should I use them?

There's no set number of quotations that you need to know for the exam and, when it comes to learning them, less is definitely more. It's more important to have a small collection of quotations that you can do a lot with i.e. say a lot about. You can grow answers out of your quotations. For instance, in Act 3 Scene 3 of The Tempest there is a tiny stage direction which is super easy to remember: 'Prospero enters from above, invisible' This would be a really good way to begin thinking about questions of power in The Tempest. Think about the power he has when he can see but no one else can see him - like a prison keeper in a panopticon, he is somebody under the radar. Think about the kind of power you have from being above everyone else. Like a bird's eye view. Think about how that might look on the stage. Is Prospero just above the actors on stage, or is he above the audience too? Power and sight are two important themes that come into play here, but you could also use this quotation to think about positioning and character relations - Prospero is estranged from the other characters here. Perhaps power is a lonely thing to be. You can easily write a paragraph about this one stage direction. Practice teaming it with other quotations that make you think of Prospero's power or lack of power. Can you think of a way in which he could be seen to lack power?
