Can I update my essay after submitting common app?

I’ve already finished my common app essay, but it’s really not that good, and it definitely has room for improvement. I plan on applying to a school ED though, and I was just wondering whether I can update my essay for regular decision?

If you’ve already sent your Common App to your ED school, than you can’t update that specific application. But you can edit your essay and then send it to other colleges.

This is new for this year. You can have as many edits as you want. You cannot change the one you submitted.
