All SNI divers (adults and 'nauts) must complete the AAUS test with a passing grade (80% or higher) to participate in SNI open water dives. Part 2 of the AAUS Test includes 56 multiple choice questions about diving physiology, diving environment, diving skills, emergency skills, and the SNI diving program.
This is a TIMED CLOSED BOOK test. See moreYou have 60 minutes to complete it.

Rate this question:
Do not use the tank and immediately call the dive shop that filled the tank so they can investigate the problem.
Have your buddy keep a close watch on you throughout the dive.
Immediately call the dive shop that filled the tank and check on the compressor maintenance schedule before using the tank.
Go ahead and use the tank at depths of less than 30 feet.
Rate this question:
Will require more weight to be neutral near the surface, and more air in the buoyancy compensation device (BCD) at depth to remain neutral, than a thinner wetsuit.
Will lose positive buoyancy as it ages (due to crushing of the neoprene), requiring the diver to use less weight for neutral buoyancy as the suit gets older.
Can be useful even in tropical areas, but is necessary for safely diving in cooler water temperatures.
All of the above.
