Blue Star Learning, San Diego

Although Blue Star Learning has a 20-seat classroom—complete with surround sound and individual computers for students—its courses accommodate a lot more than 20 people. That's because of live online sessions, which pass on the same IT knowledge as the in-person sessions in San Diego. Blue Star's curriculum encompasses a wide range of computing skills, from Microsoft, Cisco, and Adobe programs to cloud computing, QuickBooks, and Linux. It also hosts classes on how to successfully run a business, even if you haven't yet mined a set of cufflinks.
