If so, you've done a nice job of revision. The final step in the process is proofreading and editing. Editing is what editors do for magazine and book authors. That is, they proofread. Then they send it back to the author for corrections, or they make them themselves.
Many people are deathly afraid of writing because they think it's all about spelling and grammar.
Those are very important, but they are only the final stage in a long process. It is the way good writers write, most of the time. It is also the only method of writing instruction that is based upon research and real knowledge about the actual writing of good writers. I want your best. I want you to be using the writing process so that you can continue to write well when you leave this class.
