Need overview of how ALEKS work

[FinancialWorld]

Well I've heard a lot about the ALEKS testing but haven't taken any or checked very deeply into them. I know there is a plethora of info on the forum about them, but I would like to get a condensed version from you all.

Here are my questions:

1. How much do they cost?

2. How do they work (Do you need textbooks, is it all online, is there a time limit, how long does it take etc.)?

3. Will the credits transfer straight to TESC (I know that only the ACE accredited courses will transfer)?

4. I'm planning on taking Intermediate Algebra to fulfill some general electives. I've taken CLEP College Mathematics, CLEP Precal, and DSST Statistics. Does anyone know if the credits for these will conflict if I take Inter. Algebra (I'm a BSBA student at TESC)?

Any info would be appreciated, and if I left anything out, feel free to add to it.

Thanks
