Phil,
Several years ago I asked all on the listserv to send me their success
rates in as many of those courses as they taught. When I did what you
said I had to go to a cohort of 10,000 students so I could report
anyone likely to pass precal. I think it was about 4 or 5 out of
10,000. I did this because a lady transfered from Ark. to Tex. and
they wouldn't let her take College Algebra because her SAT was a point
low. I let her take it at a distance and she did quite well - a B, I
think. It started me thinking.
