Submitting Research Supplement

<p>On Columbia's website it says this:
If you plan to submit supplementary credentials, please follow the instructions below instead of those in The Common Application Arts Supplement. Applicants should not submit the Common Application Arts Supplement. </p>

<p>But then the two subtopics are "Science and Engineering" and "Creative and Performing Arts." If I'm submitting a science supplement then should I still follow the common app? I can't tell by the way its worded if it means not to follow the common app just for arts supplements. I need to know whether I can submit my research supplement online or if I need to mail it in. Thanks!</p>
