When you go to your college course do you have a button top right
turn editing on? If you don't then stop right here because they haven't made you a tutor on the course yet
If you do, then click it and you will get drop down boxes in each section. Choose a section and click "add a resource" then "link to a file or website" Name your syllabus and then lower down where it says location, click the "browse" button , browse your pc hard drive or usb stick for your syllabus, upload it and then -important -click "choose" in order to display it. That will take you back to the editing screen;scroll down and click "save and return to course"
