"The material in this course is very condensed. Data Table lecture was very much a copy of someone else' information on the web and was so terse, I would imagine even people from programming backgrounds had had to listen to it many times just to understand what was going .  Expect to put in good 8-10 hours a week into this course if you want to become proficient in course' material."
