In the English test you have to answer one question about Shakespeare. This question will be about two extracts from the play you are studying. You need to know the two extracts well, but you should also have a good idea of the basic plot of the play.
This Revision Bite gives you a summary of Richard III and shows you how the two extracts fit into the overall story.
Don't try to remember every detail of the play. Instead, learn the basic story and then concentrate on what the characters are like. You should also think about how an audience will react to the play, and the themes it deals with. Some of the themes, for example, are power politics, crime, punishment and of the rise and fall of a man who will stop at nothing to become king.
