The conclusion part of the essay is the most important. With the support of the previous paragraphs, the conclusion must not start a new argument nor can it support the positive or the negative side of the topic. It must restate the thesis from the introduction paragraph and make a general statement about the facts that have been discussed in the essay. In other words, the conclusion should be unique and remain neutral. It can be a good idea to end your essay with a personal opinion about the topic. The opinion should be supported by the information provided in the previous part of the essay.
The blank screen or paper in front of you while drafting essay is the most difficult part of the process. You must sketch out a plan before writing. Once you have written down your points, start assembling these points. Give each point a logical heading; this will help you to elaborate your points. These will later develop into paragraphs of your essay.
