The Documents tab is only available for certain programs. Uploaded documents will only be visible to that specific program. Documents that do not have a red asterisk are optional and do not need to be uploaded for you to submit your application.
Contact the program directly if you have any questions about their specific requirements.
If your program provides a PDF form to fill out and upload in this section, you must save and upload it as an image. Depending on your computer's operating system, there may be multiple ways to do this; a Google search can point you in the right direction.
Once your application is submitted, you cannot re-upload, update, or edit the documents in any way; however, you can upload new documents.
