Thanks for the response.
In this case, it would go to the postbac program reviewers. Just wanted to put my best possible foot forward and try to make my essay and application as strong as possible; as if it were going to a med school, especially for the really competitive programs like Goucher w/ strong linkage connections. From what I've been hearing, a similar version of my PS, rec letters, etc. will likely be forwarded over to linkage schools. Though, you are very right that the programs will help me edit them! Maybe I'm being a little over neurotic here lmao
