I got an email from a student who submitted part of her regular application on paper, but who also had an online account. She thought she could work on parts of her application online.
Perhaps that will be possible one day, but for now, you must choose one method for submitting your part of the application: paper or electronic. Now, if you submit your application online and want to mail supplements, that's fine. However, if you mail us an application, you should not continue to use your online account.
