So last night I completed and turned in my Common App to Boston College before the 1/1 deadline. Today (1/2) I was back on the Common App website and it showed the application as submitted but not the BC writing supplement. I clicked on the yellow circle under the writing supplement and submitted the essay I completed yesterday. It didn’t notify me that I submitted the supplement late but the timestamp says “1/2”.
Did I just screw myself over? I’ve seen threads with issues similar to mine and am hoping anyone with a similar experience can advise me on what to do.
*The writing supplement was already written and saved on the Common App. All I did today was press submit and digitally sign the contract.
Make sure to call the college when they open and tell them about your specific situation.
Uhhhh same here. I submitted the application really early but I just realized that writing supplement and application need to be submitted separately. And I forgot to submit the writing supplement:((((
What ended up happening. The same thing just happened to me. 
Ended up getting waitlisted at BC. Probably just because of the competitiveness of the school but who knows who knows for sure.
