Good discussion. I also add here.
First of all select a wide range of topics. Write them on a page. Take out that page. Select a topic. Set a time duration of about an hour. Make sure you complete your outline in that stipulated time-frame. Now, try to understand the demand of the topic. A quotational topic is always tricky; try to find out what the examiner asks you. Once you become clear about the crux of the topic, make a thesis statement. Now your main heading should be based on the demand of the topic. If you successfully build the main heading and give enough but relevant material, i assure you will pass. However, if your main-heading goes irrelevant, you'll be in trouble.
Another thing to keep in mind; a quotational essay does'nt usually ask you to write causes, consequences, suggestion. It rather wants you present a relevant, organised idea that can adequately answer the topic.
