To analyse a quote, you should first of all ask yourself 'what is the quotation about?' It seems a simple step but it's something you should always include. Then ask yourself, 'are there any literary techniques being used?' Show off your knowledge and mention if a simile is being used, or hyperbole, or emotive language etc. Then always explain WHY. If this is too difficult to answer, maybe ask yourself what the quotation would be like without the literary technique, and compare them. An examiner wants to know that you understand the quote, that you can explain why the writer has used it, what techniques have been used, and to what effect.
