This is in the US, in case it's unclear.
I'm interested in teaching math at the 2-year college level. I have an interdisciplinary MS with a strong engineering focus. I see openings that require "a master's degree in a related field with at least 18 hours in Mathematics".
I looked around for advice and everyone's talking in terms of earning a complete degree.
Is it possible for me to earn these hours in a way that would satisfy (at least some) hiring committees, without having to get a whole extra master's degree?
