Thanks for letting us know.
We are so sorry you are about to flag a couse, but we appreciate you doing so. It is very important to us for you to be happy with the content on CGCircuit, So as soon as we receive your reasons for flagging this course, we will look closely into it. We will let the instructor know and take the necessary steps to fix the issues.
Please try to be as detailed as possible with your comment. A sentence like the following "I don't like this course", is not very helpful. Instead if you tell us all the reasons why you don't like it, we can take the necessary steps to make it better.
