Important "extras" question!

First of all, I’d like to thank all of you. You’ve been a huge help.
My question is this: is it too late to enter in early action supplemental materials on the portal? I have a “performing arts” recording i would love for the admissions team to see, but is it too late?

Thanks

I’m not sure, but keep in mind your last-minute “extra” may be compared against conservatory-level artists who may have planned and worked many hours/days/weeks/months on high-quality studio recordings that are not only of superior artistic and technical quality, but also cohesive to the applicant’s overall application and message.

If it was not important enough to include originally, why is it important now?
