Now that you have a list of essay topics to choose from, select the one that you feel you are most comfortable with and start working on it. As with any essay, research is key but even more so when you are writing a dissertation. There are plenty of resources available that you can use to write a first class statement. Make sure that every statement you make is backed up by a relevant theoretical concept. Maintain contact with your supervisor throughout the writing process to ensure that you are on the right track.
