Startup Idea : Customized Coding (computer adaptive learning)

Basically, this is an online learning environment for coding that meets your skill-set wherever you may be. You start off with about 100 questions to assess your subjective skills. Using predictive modeling, you start a lesson that hopefully matches your skill level. At first, you may start with a lesson that is too easy or too hard and the computer learns from this and sends you down to an easier lesson or up to a more difficult lesson. The more users, the better the predictive algorithims. There's room tons of social, content marketing as well as gameification. Plus, when users get good enough, they can start working on low-level programs from companies. Companies can then assess skills and make hiring decisions.
