The difference is that with Khan Academy, Coursera etc. you need self discipline. With Lambda you have a coach who expects you to be at your computer at 9am every weekday, and who has a strong financial incentive to ensure you learn. Plus in time a Lambda qualification may become more respected by employers than a Coursera degree.
