If you can't see any modules at all in your blackboard area you may still need to complete some part of the enrollment process, only when you have completed stage two enrollment will you have full functionality in blackboard. If you have only just completed your enrollment your associated modules will show after the next update (usually run regularly throughout the day although occasionally may take until the next day to show).   

If you can see some modules but not others then please contact your tutor, as it is your tutor who will make content available to you.
