The Submitted date you see for each item in your Checklist is the UTC (Coordinated Universal Time - abbreviated as UTC - is the primary time standard by which the world regulates clocks and times) date/time used by our online system for all member institutions. The institutions are aware of this and as long as you are able to submit the form, they will receive it. We accommodate the deadlines for various time zones around the world.
If you have any questions about the submission date and acceptance of an application item after the deadline, please contact the institution directly. You can find the contact information of the institutions here: https://www.universalcollegeapp.com/colleges.
