New to the forum, looking for some advice on BA CS vs BA Math

[TrailRunr]

It appears Boston University has either postponed or discontinued the edX courses in math, which would have given you three of the required five upper level courses. Because of that, you will have to take five UL math courses at TESU or some other four-year school. Linear algebra, multivariable calc, and differential equations all count as UL credit if taken at a four year school. APU has a good selection of UL math classes including true UL math courses like real analysis. I think there are lots of options out there for UL math courses.

As far as TESU CS, the fastest plan has three MIS/cybersecurity exams which aren't good preparation for OMSCS or highly technical jobs. It also includes linear algebra which will be useful at OMSCS. It's very tough to find cheaper online CS courses that count as UL (honestly, I don't know where you could find any UL CS outside of TESU without spending more than TESU tuition). The UL CS TESU courses won't help much in surviving the tech interviews which is the most important factor in getting a job. TESU BA CS is ideal for experienced IT folks who just need a CS degree for HR purposes. On the other hand, I don't think it's great option for those who don't have a lot of IT job experience.

My signature has the degree plan I used to double major in CS and math. You might find it helpful.
