Provide the same grade to all the active members in your group with names on the top of paper for the original and revision submission.
Don't just copy and paste somebody else's work without that person's permission. That is considered to be plagiarism. Also, if you quote somebody else's work, you need to follow the appropriate citation rules (APA, MLA, or Chicago Style). If you are not sure about it, make sure with me. Respect each other. If that happens, I will follow guidelines from student standards of conduct.
