If you have already uploaded your assignment, please delete it and reupload it.

Technically, that's not necessary. It's enough to delete it from the collection and temporarily stick it into an unrevealed collection (http://archiveofourown.org/collections/Unrevealed_drafts works well - don't forget this step because otherwise your fic will be temporarily visible!), save it, and then edit it again to add the collection back. Which is not ideal either, but some people might prefer it to deleting and doing everything from scratch.
