I last minute decided to apply early to Purdue University. I would have been set to go at 11:50 but realized there was a section of the common app I hadn’t filled out yet (courses and grades). I plan on calling their admissions office later to see if they have any grace period for this kind of stuff. It isn’t my only early action school so it won’t be the end of the world if my application went straight to the trash, but what should I be expecting?
Usually there is a bit of a grace period. You can contact admissions and ask. Worst case your application will go into the RD pool.
Nothing will happen. It’s not like adcoms were in the office at midnight 
UPDATE: I called the undergraduate admissions office at Purdue and I was told that my application was fine. Thanks for the support guys
Good luck, hope you get in!
