Did I mess up big time? UMich Transfer Applicant

I recently got an email from umich telling that they were missing my gap year explanation. (I forgot to include it in the common application). I quickly uploaded it via the portal, but now I am concerned that I have effectively ensured that I would be rejected. Is there still a chance for someone like me?

Call and ask if they received it and if there is anything else they need as a followup. As long as you sent it in, in a reasonable amount of time after the request you should be fine. They were just completing your paperwork so they could start the evaluation process. It’s a very normal procedure.

Don’t read to much into things like this. Just give them what they want.

Thank you. I uploaded the explanation immediately after I received the email.
