I got deferred from Cornell and I wanted to send in an additional essay about my continued interest and a job that I recently got, would I submit it at this page https://forms.admissions.cornell.edu/webform/admissions/submit.php ? It just talks about letters of recomendation so I’m not sure if I send it online or by mail.
I’ve read online that people sent a lot of other things, aside from recommendation letters, using the site you posted.
