That's the problem: there is no way to subjectively grade a math test, no way for poor academic performance to hide.
Going to a university is a waste of time and limited resources for artists, poets, basketball players. The cost exceeds any return on investment. Unfortunately they are incapable of doing the math on that.

You might want to reconsider that, at least with the way ‘math’ is now being taught at the public schools. They easily got around that problem.
But, yes, your point is correct for tests that actually measure mathematical skill.
