Lessons not working

I have been trying to learn R, but today when I try opening up a lesson (the last one I was on was just the first quiz of the introduction module) it won’t let me open it at all. It just keeps taking me back to the syllabus every time I try to open a lesson.

It sounds like they were working on something behind the scenes at CC. Other people were having issues too.

Best thing to do is to report it to CS via the Get Help link on the main page here.
