Well I've taken all the practice exams I could for Statistics.

DSST: 8/10 (80%)
ECE: 20/25 (80%)
TECEP: 12/20 (60%)
AP Statistics: 11/18 (61%)

I'm fairly confident. I'll just keep plugging away at the material until Wednesday and post my results then. Thanks especially to dhlvrsn. You've been a tremendous help. I greatly appreciate it. With a little bit of luck I'll have one less class soon enough.
