I used to the following link and scored 57 without any previous knowledge of Psychology. Good Luck. http://www.freeuniv.com/lect/psypage.html
I have seen that webpage. I don't know if they have updated lately, but I seem to remember that alot of the links are broken. This is what I used. http://www.mcgrawhill.ca/highereducation/digital+solutions/index.php They have online "primers" for a bunch of different subjects (including intro to pysch). Its not tailored specifically for the CLEP, however it helped me a quite a bit. Regards, Bill
