It’s a bit of a stupid question, but I am lacking in demonstrated interest, so if I can add the Youtube channel to the list of ways I’ve learned about Columbia on the application, I’m all for it. Thanks!
It could fall under there, or you could put it in “Other”. Either way, demonstrated interest is not considered in the Columbia admissions process. http://www.collegedata.com/cs/data/college/college_pg02_tmpl.jhtml?schoolId=399
