How do you make conclusion

Sum up whatever you wrote into one short paragraph.

Explanation:

Include a brief summary of the paper's main points.

Ask a provocative question.

Suggest results or consequences.

Avoid:

Ending with a rephrased thesis statement that contains no substantive changes.

Introducing a new idea or subtopic (although you may end with a provocative question)

Focusing on a minor point in the essay.

Concluding with a sentence tacked on to your final point.

Apologizing for your view by saying such things as "I may not be an expert" or "At least this is my opinion."

Attempting to make up for an incomplete structure. (If you say you will discuss four books and only attempt a complete discussion of two books, do not try to cover the remaining texts in a concluding paragraph. In such a situation, it's best to limit your paper to topics you can realistically cover.)
