The idea of setting essays is to offer you the chance to make a longer, more complex argument. Nonetheless, in the model we recommend, the fundamentals remain the same. In each paragraph, a flow of main idea (thesis) - explanation / reasoning (justification) - evidence / example (support) is an excellent structure to use. If you read through academic writing, you will find this structure over and over. The same is true for professional writing. There are of course other structures, however this one always works and makes you sound concise and clear.
An essay has conventional sections that it is wise to follow. These are an introduction, main body and a conclusion. The 'LSE' essay structure can be described as 'say what you're going to say (intro), say it in detail (main body), say what you've said (conclusion)'. Although this may appear repetitive, it offers the reader great clarity. Also, if you think about the executive summary, background, analysis and conclusions / recommendations sections of a business report, you can see that a similar structure holds.
In your essay, try to follow this structure for your essay sections.
