freelance, a wealth of information is at your fingertips, in the black menu bar at top of page.
In the "Credit Education" is a wonderful pie chart graph, which demonstates the weight of the various components of FICO scoring.
Under "Support" is an incredible amount of info for you. In the link titled "Understanding Credit Scores and Reports" are 2 downloadable booklets in .pdf format, titled "Understanding your FICO Score" & "Identity Theft & You".
To me, these 2 should be REQUIRED reading in a college level economics course.
Hope that helps. Those 2 menu tabs sure has helped me. Good luck to you
