I am choosing between taking a distance course for Biology and taking the CLEP Exam. Can anyone share their success in passing the exam, ie college text, study guides, or test preparation? This will be my first CLEP Exam. How long did you study for the exam, considering it is for 6 credits? I have 98 credits and I am more motivated than ever to complete my degree. After I pass a few exams, I plan on enrolling in TESC for the BSBA degree. The comments on this site have been very helpful. Thank-You.
