TEST FLIGHT GETS MORE PILOTS: Udacity and San Jose State University are extending its pilot for for-credit classes to include Intro to Programming and Intro to Psychology, both of which will be open to 1,000 SJSU students. Enrollment caps for the first batch of math courses, announced back in January, will also be increased. Udacity co-founder Sebastian Thrun shared in a blog post that the initial pilot has seen "85% retention going into midterms." It's not quite the 100% rate that he boasted about at a recent talk, but it's getting there.
