Yes or no. 
Do they make a difference?
If you were the one in a hundred who finished the course with over an 80% average it would be of interest to them if it’s clearly in your field of passion.
It won’t be a hook or a big factor but it can help build on your overall theme.
However, don’t even bother unless you would take the MOOC for its own sake. If you are taking it just to pad the resume it won’t be worth your time.
I’m not… I took 3 so far, and I was just really wondering if they look good to colleges. A friend told me today that they go on our transcripts, but I had no idea until today. So…
How would a MOOC go on your transcript? Do the ones you are taking have final tests? How would your school get the info?
