I'm about to graduate with a degree in Computer Science and going into the degree I was very insecure over my competency in mathematics so I took a B.A. over a B.S. This was also for financial reasons since a B.A. allowed me to graduate a year early.

Turns out I'm not bad at math, I just didn't prioritize it and suffered from serious anxiety issues. I actually really enjoy the subject and took a Calc class and really liked it.

I'm graduating soon and need to get a job, but I want to learn more about it and prove some level of competency in math. How can I reasonably get a math degree post graduation without going into massive debt? Is there anything else I can do?
