Kali,
I talked to the professor about this last week, as I was concerned as well. He said that Coursera’s policy had changed and that he couldn’t open registration until one week prior to the class commencing, which I think sounds odd…and may hurt registration numbers. I’m now sure, however, about why the dates aren’t announced on the site yet. I may send him an email to verify that course is still on for June 6th.
Best,
Gui
