We recently had a parent workshop on the advantages of CLEP testing. CLEP tests are credit earning exams offered by the College Board. They are somewhat similar to AP testing. Each college or university has their own set of rules as to what CLEP credits they accept.
I have attached the presentation that was shared at the parent meeting. It has been changed a bit to give you the basic framework of the CLEP testing process. It is definitely worth some investigation. It may save thousands of dollars.
