I’ve seen Berklee offer some free programs online before, but this is the most comprehensive listing of courses I remember them offering. Thanks to /u/nostrongfeelings for sharing this.
Here’s the complete program at Coursera. Ignore the “sign up” links, as they’ll charge you in order to get a certificate at the end. If you don’t care about the piece of paper, clicking the individual course names gets you in for free.
Have fun, learn stuff.
