Easy to fix: test applicants independently and don't let dummies in. Don't waste my tax monies trying to bring them "up to speed".
My students can do math. The problem is they cant pass standardized tests.
But they tested graded 4.0 in high school in math. High Schools are passing failing students, and that is a problem.
A problem which college could go a long way toward fixing - by discounting grades from HS's which engage in that practice. (Admittedly, I suspect that's most HS's these day.)
