Welcome to Wikipedia. We welcome and appreciate your contributions, including your edits to Course Hero ‎, but we cannot accept original research. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. Thank you. Kuru  (talk)  11:45, 19 October 2017 (UTC)
