<p>I know that this sounds like a dumb question but I am new in the US college application process so I really don't know. So after submitting the CommonApp, how can I submit the Supp App to Columbia? The Supp App for Columbia is a pdf file, isn't it (<a href="http://www.studentaffairs.columbia.edu/admissions/applications/common_app_supplement.pdf%5B/url%5D"&gt;http://www.studentaffairs.columbia.edu/admissions/applications/common_app_supplement.pdf&lt;/a&gt;)? So how can I write on it and submit it online? Or do I have to print out and send to them by mail? And also how long should the short answers be? </p>

<p>Please help me. Thank you.</p>
