This is a super easy way to give common feedback for common mistakes. I give this to the kids when I pass back their first essay of the year. I have them paste it into their comp books. When I pass back the essays, I have them use it to see what they need to work on. It saves me a ton of time by not having to write out the comments, just numbers. I also have them count how many of each kind of error they make so they can really see where they are struggling. They have to revise the essays and then I grade the by the AP Lit rubric assigning it a score of a 1-9. This is an extras step I don't always do, but at least once a 9 weeks.
