I've seen more than one post from people who are worried about being able to remember statistics formulas. I'm taking a self-paced course from Penn Foster that Excelsior has approved for my BS/Liberal Arts degree. There are a total of 4 exams, one of which is the final. All are open book, and 3 are not proctored or timed. The final is timed at one hour, has approximately 20 questions, and you have to find a proctor for it. The material covered is less extensive than the DSST Statistics test. The course can be ordered by calling Tom Hunt at PennFoster: 800-233-0259, ext. 4104.
