a) That college is not affordable or
b) Students are not ready?
It's standard procedure to have "placement exams" for entering freshman to decide which math and English courses they are prepared to take. In many cases, they end up in remedial courses to qualify for classes that are required for their degree. The remedial credits cost the same as any other classes and consume time to complete. It's sad to see a college freshman assigned to a math course that covers algebra as taught in 6th grade elementary school.
At UCSD, the first freshman physics course in simple Newtonian physics required being able to do basic differentiation and integration. By the 2nd course (electricity and magnetism) you had to derive the equation for the magnetic flux of a solenoid (integrated over the length of the wire and accounting for the geometry). That's hardly in the realm of reality for someone who needs remedial math.
