Common App Supplement Question

<p>For the Common App, Cornell has a "main supplement for all students" which can be submitted electronically, and then an "all other supplement forms," which are "to be completed off-line" and include the essays form and the financial aid application</p>

<p>My question is, do the "all other supplement forms" need to be self mailed to the school or is there something im not understanding here?</p>

<p>Any help would be appreciated!</p>
