Editing
                    Polishing your draft to correct errors in English. 
               Proofread to identify and eliminate any errors in grammar, spelling, and punctuation.
Don’t begin the editing process immediately after redrafting; you’re too tired!  Also, you’ll ghost write and automatically fill in the gaps because what you meant to say is too fresh in your memory.   Put it away for a day or two.
Use a proofreading checklist of grammar and spelling errors that you most frequently make.  Be prepared to read your draft several times as you check for errors.
Read your paper backwards!  Start from the bottom of your paper, read the last sentence first, then the next-to-last  sentence, etc. all the way to the beginning sentence.
Team up with a classmate and become proofreading partners.  After you have edited your own papers, swap and edit each other’s.  He/She may find several error s you missed.
Use a computer spell check to find spelling errors, but  BEWARE!!
If you write the sentence “I fell tired.”  spell check will not pick up that “fell” is the wrong word and that it should have been “feel.”  It will only recognize that fell was spelled correctly.
