I'm sorry but this is straight up a non serious reply. If you want to be in STEM you need to pass calculus, then the specific majors have their own "weed out" courses which is good. There should be some base level of competence and if you can't pass, say, Abstract Algebra then you can't get a degree in mathematics.
There needs to be some sort of academic baseline for university otherwise what is the difference between a youtube playlist and a semester worth of credits?
Can the school teach its students calculus or does it take money from people, fail to teach them calculus, call them “weeds,” and kick them to the curb? The responsibility runs both ways.
I am definitely not saying that students should pass without learning the material. I am emphasizing that schools and instructors also have a responsibility to teach their students, both morally and financially. Just because the norm is to behave amorally and with greed, that doesn’t make it proper.
