When I was a college professor, 80% of freshmen failed placement tests and the college spent a year or two in remediation. That filled the seats in classrooms where the ecxpression was that we just needed warm bodies to keep our programs going. A lot of what the uniopns favor is really just featherbedding to make work for more unqualified "teachers". We would not need universal preschool, smaller classes, so much jr college, if qualified teachers would just teach the K-8 curriculum like they used to.
But at least most of the students out in Cali vote Democrat.
Be happy in your ignorance!
