So I've been turking for over a month but for some reason I JUST CANT FIGURE OUT the Rubin hits. I look for the course catalog and sure enough I cant find ANYTHING. For instance , one was for skyline college - discrete mathematics. I found the catalog on http://www.skylinecollege.edu/catalogschedule/assets/documents/catalog20122013.pdf but cant find ANYTHING to do with discrete math. Any helpers?
