How to Edit your writing
To edit your writing well, you need to understand some basic concepts about writing. Sometimes these concepts are called grammar, mechanics, or conventions. Sometimes they are called rules, but really these rules are just patterns that good writers try to follow so they clearly communicate what they want to say to readers.
Anybody can be a good editor. First, you have to know what's important and then you have to reread your work carefully. Everyone-especially teachers-appreciate a writer who rereads and corrects his or her work.
