Common App deadlines, does it take a few days to process?

If a deadline is on 11/1/2015 when do you actually have to submit the app by? Common app said it can take a few days to process. Already sent transcripts and ACT scores.

haaallllllpppppppp

Submitting the app on the deadline date would still work, but not recommended.

Sometimes the system goes down on busy days. I’d submit a couple days early if I were you.
