There was some link a few weeks back about the low completion rate for some online coursework being abysmally low. This is HN, I would expect a hundred anecdotes from those who have succeeded against the traditional educational system in CS. But are there studies or other evidence this is more then survivorship bias? Is any study following dropouts, non-BS grads, bootcampers and online students in the industry over time and counting from the total population who registered for CS 101?
