You mean just like high school? That is why entering freshmen have to take all those remedial courses. I guess we could offer the remedial courses when you go for your masters or doctorate now, (assuming students will have to pay for those.)
Public education coasts between $10-$11+K a year per student. Imagine if parents were responsible for paying the full load of their kids. I’m sure a lot more kids would be doing a lot better in school.
