Try and save all you got from the internet,then read and re-read.
Get the area that identified with your assignment.
Read and translate in your own words.
You can now post it here.I know you will definitely get help.

Yes, thanks, Oluwayemisi, for that great, succinct advice!

You know, when you research something on the Internet, you find a lot of different articles, but what is the real truth of the situation? That is how to write a good paper: find out the truth, and then explain it in the intro paragraph. Then, quote some of the articles to show what you mean. In your paper, you use the name of the writer, or the title of the article, and you write, for example:

One writer explains that this was the "most important battle in the war" (Roberts 14). Roberts writes, "No one expected the battle to take place when it did, and the consequences of the surprise may have changed the course of the country's history" (17).

But maybe you find other authors who say it that this battle made no difference in the outcome of the war, so you have to compare them and come up with your own opinion. So, it is actually really cool.

In your first paragraph, tell your opinion, and in the body paragraphs tell about the articles you read. In the last paragraph, tell about your opinion again and mention the main ideas from the paper one last time.

In my experience...if I have found some information
I will sort out it firtly and you will find you have some idea
then think which one is the most important which one is second...
then you wound know how to start
