Lawman:I finally passed ALLLLLLLL of the written exams. None of them were easy. Not rocket science, but not easy.
The Wheel would be easier to teach than the tables for new divers. What I didn't like about it is as accurate as the person reading it...I used a magnifying glass and that helped.
After completing the last test my instructor told me to be at the pool in 3 hours for the first pool instruction. Two hours after that we did the equiptment exchange! Passed and didn't drown. Now comes the 1200 meter cement block, rescue breathing buddy tow.
Congrats! I'm going to try to finish up the exams this weekend. Watermanship skills are done. Just have the gear exchange and class assisting. There aren't a lot of classes around here, so that might take a while. I agree with you on the wheel. I've never used one before, but I like it.
