To write a college paper using APA style, you must first know what kind of paper you are to write. Then you can determine what the parts of the paper need to be to fulfill your requirements. Next, APA has some general instructions about spacing, typeface , margins, and other things you will need to know if your class assignment did not specify. Be careful with citations because they are so many ways to write those. Keep up with all bibliographic information. In fact, check out the rules of APA Style, in the book, the Publication Manual of the American Psychological, or online at.
