At my school CIS was just CS/programming lite, I imagine at different schools the degree could be wildly different though? What kind of classes did you take?
Yes, it was CS/math/programming lite with extra courses in more IT infrastructure - like networking, security, penetration testing, compliance, project management, forensics, incident response, etc.
I did take calc 1, linear algebra, physics 1 with calc 1, discrete math, algo/data structures but that's about it.
So no software engineering (architecture) or programming courses? You can probably learn what you would learn in those classes by yourself if you find the right resources and are a self learner. Most people will not care about your degree if you can prove you have the skills they need.
I know plenty of devs without even a BS at all. I think you should go for it, and try for a job and only go back if you really are having issues. Just make sure to prepare for the interviews.
