CPR for the Professional Rescuer

I've just returned from the Badger Chapter American Red Cross, where I recertified in CPR for the Professional Rescuer. It was a small class and we burned through the skills tests by combining all the scenarios that we could into three long ones (adult, child, infant), thus avoiding repeating the very basics ("check the scene to see if it is safe") over and over. I have an in-the-water skills test on Wednesday to renew my 3-year lifeguard certification. It's hard to believe it's been that long. It's also hard to believe that the certification I earned for CPR/AED in May is completely redundant now. I couldn't have avoided it, but I sure wouldn't mind having the money back.
