<p>I actually do think it’s possible to find a school that will take someone on in a Master’s program in CS without any underlying experience, but it’s probably going to be a less selective public school AND it’s going to be conditional on doing some remedial UG work before starting grad studies. It’s either that, or find a school that will accept all your previous gen ed work towards a BS, that way you only need to take the comp sci and possibly the math courses. I’m thinking two years for either path.</p>
<p>A quick Google search turned up this - it addresses this very issue. It’s Northern Illinois University.

<p>A Master’s starting from zero would be 13 courses, which you should be able to comfortably do in three semesters and maybe a summer.</p>
