I took the CPC exam to be a certified medical coder today. It's a 150 question exam with a 5 hr 40 min time limit and I managed to finish it. A lot of people run out of time before completing it. I finish school the end of next week and the results for this exam should be posted week after next. It has a 40% fail rate and I am really hoping I passed it on my first try. I really don't want to have to take it again.
