In short, yes. When you select the Revising and Editing service, we will check your paper for anything and everything that could be wrong. This includes content and organization as well as grammar and spelling.
The long answer is — mostly. If you select Revising and Editing, we will send you back your paper with our suggestions for how to improve anything and everything. We encourage you to take these suggestions and then take another stab at your paper. Our suggestions may spark an idea that you want to add in, or you may decide you want to do some further re-organizing after re-reading your writing. This is all completely fine, and hopefully, you will do that — it’s your writing, after all! However, once you do this kind of work, you probably will create some more spelling/grammar issues. It’s just the nature of the beast. (We do it, too. And yes, we get our friends to proofread our writing, too.) Therefore, you will need to do a secondary proofreading after you’ve finished doing those big picture changes. You can do this yourself, ask a friend, or send your paper to us for just proofreading this time.
However, don’t let this worry you or stress you out that you’ll have to pay for multiple services every time you write a paper. If you receive our suggestions on Revising and Editing and are happy with them as they are, then congrats! Turn your paper in, and be done with it.
