Has anyone here who has studied Human Resources Management taken the CHRP/CHRL exams?

I just recently finished my Bachelors Degree and I now want to pursue a CHRP. However I'm missing a course which wasn't required for my degree. I can either return back to school as a non degree student and do the course or do a challenge exam. My question is that is the challenge exam one exam that covers material from the 9 courses or is there a challenge exam for each of the nine courses and I can take a exam for the course that I'm missing. Another thing is for the course by course approach, for finance and accounting it shows Introductory Financial Accounting ADMS 2500 + Introduction to Management Accounting ADMS 2510 so is both required or just one?
