CSM Math - what's it like?

[inoele]

Can anyone describe how CSM math works?  I mean, for $39 it's a pretty attractive way to earn the basic math credit if it's accepted.  For reference, it's for my son, who will be doing the competency-based Organizational Leadership degree at TAMUC.  I'm waiting to hear if they will accept the course. He's not great at math and he's just looking for the easiest way to get credit.  His other options are ASU Universal Learner College Math (because it's nice that he only pays $25 until he passes) or SDC College Math.
Any information will be helpful.  How does the course work (videos, self-learning in a book?).  How long does the course take, approximately?  Is it fairly straightforward or is it quirky or confusing?  Any information you can share, please!
I looked and didn't see much about HOW the CSM Math works, just that people have taken it - so a review of it on the forum would be helpful.
Thank you!

My son who is 11 took the CSM course combined with the career exploration component. He finished it in about 15 hours. The course teaches math by giving you problems to solve that graduate very strategically from one simpler to harder skills. You expect to mess up, as you learn through your mistakes what doesn't work to solve the type of problems you are working on. You cannot move forward until you master a skill. Sometimes they will let you come back to a topic later if you are really having a hard time passing something. There are no videos or audio. It is pure reading. After each topic mastered, the course affirms you by letting you know how many average adults cannot do the skill you just mastered. It is an excellent review of basic arithmetic skills needed for daily life. I found the career exploration component provided a nice break from the math and really taught awesome skills to help someone figure out what they want to do as a career. I think it is the perfect math to take before Algebra, as it double checks all basic skills and teaches them in an interesting problem/challenge type of way with lots of affirmation sprinkled in to help you feel confident. It was my son's first college credits he earned. I recommend for middle school, high school, or adult. It does transfer into some schools as "mathematical reasoning" and can satisfy basic math requirement.
