When your facilitator provides feedback on your assignments this feedback is sent to your email address.  If you do not get the email, you may access the feedback online.  

Go to the course that you are taking.  On the left panel look for the ADMINISTRATION block.

Click on the GRADES selection in this block and you will see a screen that contains the grades you have received and any feedback that has been provided.  You will see feedback on a draft, even if the draft was not assigned a grade.
