Study - its the 4th of July and I've done lots of studying. I've received 22 lbs of books and materials I need to review. I'm about 1/2 way through the Divemaster manual and I've read several sections of the Padi Enclopedia of Recreational Diving. Topics have included the "Chemistry and Physics of Diving" and the "Physiology of Diving".

I've completed the instructions and sample problems for the eRDP. This was easy compared to the reading and problems in the Divemaster manual. I expect the "wheel" to be much more diffiuclt.
