Where might I start when writing a discursive essay in French?

The best thing to think about when writing a discursive essay is to have a clear and defined structure, whilst always keeping in mind that everything you write must be relevant to the question you are asked. By having a clear introduction and conclusion which surround your main argument paragraphs, which are also internally well structured, you can easily make sure that you have answered the question in a concise manner, without repeating yourself.
