How to Proof Your Paper Accurately

Read your sentences out loud one by one and WORD for WORD.
Check your spelling and capitalization.
Check your punctuation.
Make sure your thesis statement is clear and is not too broad or too narrow.
Make sure your paper is well organized.
Under normal circumstances, don't use the word "you" (second person) in your paper, and be sure to look for shifts in person from first to third.
Watch for fragments (pieces of sentences), comma splices, and run together sentences.
Check for shifts in tense, subject-verb agreement, and use of the passive voice on all your verbs.
Watch out for vague pronouns and make sure all pronouns agree with their antecedent in number, gender, and case.
Make sure you used good and varied transitions in your paper.
Check your paper for misplaced modifiers and parallelism.
Check for proper syntax by avoiding wordiness, euphemisms, and slang.
