Course enrolment is handled for you by your school. In the spring, when you do your course selection for the next year, CDLI courses will appear on the selection sheet along with the courses offered locally. Your school will register you in the required courses.
To access your courses, all you have to do is visit CDLI's website and login. If you do not already have a login then click on the login link and you will be taken to a page that offers several options, including the ability to register for a new account. This account request is subject to an approval process. Once completed, you will be notified. Once logged in, you will click the link to Desire2Learn and be taken to your Desire2Learn home page, which will list all of your courses, along with any announcements that relate to you.
To access any of your courses, just click the link and you will be taken to the course home page. From there, Desire2Learn will manage the process by which you perform both the asynchronous and synchronous tools used by CDLI.
