In order to have a high-level conclusion, you need to go through 4 phases. Stating your argument (that you have reinforced throughout the entirety of the essay), stating the counter argument, discrediting the counter argument, and re-stating your overall argument. This seems complex, but it is only essentially you affirming and re-affirming your analysis and argument because you are utilising your opinion/argument to discredit the counter of it. This means that you convince the examiner that your argument is ultimately valid/the 'right' answer.
