So I bought this CE over the Xmas holiday while it was on sale. SUCKER. Yes that's me. Worst EMS CE I have ever used and i have been a certified EMT and above for 45 yrs. Do yourself a favor and choose a better provider. I am on my 3rd CE from them right now, a subject I know a great deal about Scuba diving injuries. My PADI instructor #22170 affirms I have a great deal experience with the subject matter. Format is downright laborious to listen to. Figuring out the computer system itself is down right painful, several sections ended but you were forced to do them over again to move to the next one. Hope by now you are feeling my pain for a 1.5 hr ce that has already made me listen for 2hrs and still not over.... my next problem with the format is that you can't print any of the material for future reference or later review. If I can ever get to the test I will add to this review. However, at this time I highly recommend you save your time and money a choose a different provide.
