Revisions must be submitted NLT one week after return of the graded original. In all cases, whether A or F, you must maintain a portfolio of original and revised papers. Your professor is not your editor. Your job is to read the corrected papers and figure out, with the help of your text, what the problem is. If, after a sincere effort, you cannot discover it, come for a conference.
Plagiarism is punishable by decapitation, mutilation or dismissal, at the whim of the professor.
All classes must be attended and all papers presented on time except in cases of decapitation, mutilation or incarceration. In such cases some leeway is granted.
