US History Part I: How well do you need to know the IC cards to pass??

[columbia]

You don't need 100%, strive to be somewhere in the 90's; but other than that I can't give you an exact number. It depends on if you're going the IC only route. If you (he) just want to test out and move on, go only IC and definitely get in the 90's for each set. Then you can be confident at the test site which helps a lot. If you're pursuing a more leisurely pace with other materials as well, then your IC score doesn't need to be as high.

This clep can be done with IC only. I only used IC and scored 71, but I'm a history buff (or nut, as you prefer). IC is designed to prepare you for the test while other materials may not be (though REA is highly recommended by others on this site). A side note: for most of my tests I supplement by briefly reading one of the officially recommended books that I can get from my library, but some tests IC is all I do. It depends on the exam.
Though the IC scores serve me as guide posts I take tests when I have that sense that I know the material, but that's just me; what works for him could be something different.

If you really want to learn history I recommend just getting the clep over with and studying history on your own as a hobby. You learn more that way.
