Can I take a CLEP or DANTES test in a subject that I've already taken?

This is a bit of a complicated answer. You can take a CLEP or DANTES test in any area that you want. However, your school may not count the credit towards your degree if you have taken the class before. Some schools will give you the credit as an elective credit. We recommend that you always talk to your academic advisor or counselor before you register to take a CLEP or DANTES test and before you purchase CLEP or DANTES testing materials. As credit-by-examination proves, knowledge is power!
