What advice would you give to a classmate about writing an effective conclusion?

I would advise to come strong with strong words that have the capacity to sum up the main ideas delivered in the speech and once again stress the importance of the speech material to the audience so that they do not forget the next moment. The conclusion is the last chance to make up for the deficiencies that may have existed in the delivery of the speech. Provide reasons about why the speech was important to you and how it is relevant to the audience. Reflect on the findings or suggestions of the speech so that the outcome of the speech is clear to the audience.
