A word of warning: It ain’t easy to start a computer science master’s program if you don’t have an undergrad CS major or minor. I’d need to take 8-9 courses just to qualify for admissions to SDSU, 14-15 to qualify for UCSD.

Chico State has an online second B.S. program in CS, but it ain’t cheap. ($1600+ per class.)

Consider starting with a community college degree or certificate program. Or if you’re more into the technology management side of things, consider a management information systems degree.
