Cause and Effect Assignment

Yesterday I got back my cause and effect assignment and I got a B. The only things wrong with it was that I didn't document my sources in the body of my paper. I seem to be doing better with my essays now, since I got Cs on the first two and now I get Bs. The research paper, however, will not be as easy to pass, because unlike all the other papers, 50% of the grade is based on the format and the works cited, and the other 50% is based on the content of the paper. This research paper is the hardest assignment yet. I have to have at least four sources and at least three arguments. I'm writing about the mainstreaming of children in public schools, and so far I only have one argument. I haven't yet been able to think of any more.
