Many professors expect students to write an effective conclusion. Some important tips for writing a proper conclusion are:

Summarize the Main points:

While writing a conclusion, do summarize the main points. In a short paper, main points can be summarized in one sentence and in a longer paper each paper can have its own sentence.

Avoid Repetition:

Avoid too much detail in the conclusion. The best thing would be to summarize the most important information in main points.

Avoid New Information:

Don't include new information in the conclusion; instead incorporate earlier in the paper.

Use Signpost Words:

Signposts are words that the writer uses to help the reader follow. Signpost includes words life first, second, next, finally and in conclusion.

Concluding Statements:

Papers should end with a statement that mentally brings the reader to a stop. Concluding statements might include - a brief anecdote, a witty statement, an appropriate quotation, an interesting smile etc.

In Conclusion:

Writing a proper conclusion is an important skill which many students lack. Students should avoid reputation, summarize main points, avoid new information in conclusion and use signpost language. End the paper with an effective concluding statement.
