Three Stage Editing Guide
Patricia Byrd's and Beverly Benson's Three Stage Editing Guide also provides a very effective method. This method begins with the most serious problems in the 1st Stage, continues with intermediate problems in the 2nd Stage, and ends with the problems that are the easiest to correct in the 3rd Stage.
First Editing Stage: Most serious problems
Second Editing Stage: Intermediate problems
Third Editing Stage: Punctuation and Mechanics
Don't forget to check the punctuation (period, question mark, exclamation point) and the spelling!
