With most students coming to college, that means that much of the money spent on "higher education" is actually spent on 9th grade or lower material. It's only natural to ask if it's done any good. As before, note that over 90% of remedial students don't get even a 2 year degree within 3 years:
(this is from a study called "Bridge to Nowhere"; presumably, if remediation helped them, they'd only take one more year to get such a degree).
Remediation doesn't do students much good, obviously, although their debts are just as real as for students that actually have demonstrated interested in learning.
