Check for paragraph adequacy. Read essay as you think your reader will. Rewriting Based on your revising, write a new draft of the essay. Proofreading Proofreading of final draft involves the same factors as revision. There is no excuse for errors in your papers which you could have caught by proofreading.
Typing errors are still errors.
Make changes neatly in ink. Never turn in a paper unless it has been proofread. Judge the product and the process.
