Submit Supplement Past Deadline

A friend of mine in China submitted his Common App on time but didn’t know he need to submit supplements. He just found out and submitted his supplements past the deadline. Any ways he be saved? Should he email the college, how should he address them and what request should be made? (China banned gmail recently so he couldn’t see the email that confirms submission and he can’t log in to CC to ask so I’m asking for him). Please help! He had prepared years for this.

LOL if he prepared for years then how could he not know about the deadline? In this case, the best you can do is setting your expectations low.
