Not a UND linear algebra taker, but I've taken linear algebra at another online university (IU Online) while getting a second BS in math for the same reason.
For linear algebra in particular, I'd find out as much as you can about what's actually covered in the syllabus. Linear algebra was the first course I took at IU, and it was pretty disappointing (this is a common gripe about the program in the math club group).
The UND syllabus says:
In the Introduction to Linear Algebra online course you will learn:
- How to solve systems of linear equations by several methods
- About the rules of arithmetic for matrices and vectors, including computing determinants and matrix inverses
- How to find an LU-factorization for certain matrices
- About the ideas of vector spaces and subspaces
- How to compute eigenvalues and eigenvectors of matrices
Simple Syllabus
This sounds extremely similar to mine - computation-heavy with little to no theory or proof. If you
can find a course somewhere that goes a step further, I'd go for that instead, especially if you haven't previously taken one such course. In my case, I still found it useful as a basic refresher (I had previously taken Berkeley's Math 54 in 2019 or so), but had to self-study the rest.
Also, if you don't need the transcript line, maybe just save yourself the money and self-study anyway (or take NLA pre-MFE).
