Moodle is accessed via the University homepage, either by scrolling down to the bottom of the page and clicking on the link under "Login to" or by clicking on the "students" link at the top right of the screen and selecting Moodle from the Login to options. Select the Moodle link, and you will then be prompted to enter your username and password. Once you've logged into Moodle, you will be able to see all the units you are enrolled in.
