"I have programmed in SAS before (15 years ago), so I thought that experience would be sufficient for me to take this class.  I have to say it is not.  This class is definitely not for beginners - you must have programming experience, R experience and/or both.  The programming exercises do not follow the lectures and it does not build upon concepts.  You will be required to seek help elsewhere (i.e., Stack Overflow) and answers to your questions will take days, if not longer.  So, the fact that the classes are organized by week means that you will not conclude in the time you believe you will.  I feel that this class is more self-taught than anything else.  I have decided to quit this class as it has become extremely frustrating."
