My Summer section I class ended today. The best statistic is the one for retention, 80% of those who started the class, finished and received a grade.
Of those 16 students who received a grade:
31.25% (5/16) got a A, how great is that!
18.75% (3/16) got an F, not so great but careful analysis makes it very clear why and what habits they must break to succeed.
Additionally, there were 2 B+, 1 B-, 1 C+, 2 C, 1 D+ and 1 D.
Considering this was a 6 week, very intensive accelerated course, I think this is pretty good.
