Tips to Write Perfect Answer:

Take your time and read the questions thoroughly. Pay close attention to the underlying components upon which they are based. Make a few points about each question, and then reorganise them in a logical sequence. Also, please write your responses in your own words.

Prepare an overview of your response after being more selective and analytic in your research. If you’re answering an essay-type question, pay close attention to the opening and conclusion. The introduction should include a short explanation of the issue as well as a proposal for how you want to explore it. The conclusion should summarise your answer to the inquiry. You may want to include references to other texts or critics throughout your response, since this will help to provide more depth to your interpretation.
