The final examination consists of 50 multiple-choice questions. It is given on the last classroom day of the course and precedes the open-water dives. There is only one answer for each question. There is no time limit for taking the exam. It is not an open-book exam.
The questions cover all aspects of the course. The minimum grade for successful completion of the exam is 100%. That means the diver must know the correct answer to ALL questions prior to going on the open-water dives.
There is special concentration of the use of the US Navy Decompression Table. Several problems are related to being able to figure out repetitive groups, stops, RNT, etc. Be sure to be thoroughly familiar with these concepts.
Here are sample questions and concepts that one can expect to find on the examination:

Of the following would be considered the 3 most needed in all diving situations? SPG, Compass, Watch, Weight belt, Depth gauge, Wet suit

Why are weight belts put on a certain way, and what is the standard position for a weight belt ?
You should know the difference between the following ascents and when (and if) they would be used: Alternate air source ascent; Buddy-breathing (2 people sharing 1 regulator) ascent; Emergency swimming ascent at 1' per second while humming; Blow out all air and race to the surface
Scuba tanks have what information stamped near the top of the tank?
What happens to scuba tank if it is involved in a fire?
Rank the following parts of a scuba course in order of importance: Open Water Training; The written exam; Classroom Lecture; Pool Training
What should one do to prevent lung over-expansion while scuba diving
What is the main purpose for keeping at least 100 psi of air in a scuba tank?
As one descends, the length of allowable time to avoid decompression sickness gets moe or less?
A balloon is filled with 1 cubic feet of air and sealed at a depth of 66 feet before being released. What would be its volume in cubic feet at the surface (sea level)?
At approximately what depth in seawater is 5 Atm. (absolute) of pressure reached?
What is the maximum safe rate of ascent is (in feet/minute)?
Upon ascent (coming up) and descent what will happen to the air in a BC?
Do divers generally get heavier or lighter as they descend?
You are having trouble equalizing your ears during descent. What should you do?
Tanks should be visually inspected (VTI) how often under normal conditions?
Nitrogen, and only nitrogen, may cause 2 major underwater problems. What are they?
Define exactly what the term, "Bottom time" refers to.
What repetitive letter group would you be in after spending 63 minutes at 52'?
If you had a choice, especially if you were diving without a computer, which would be preferred? The shallower dive first in a repetitive 2-dive sequence; The deeper dive first in a repetitive 2-dive sequence
To officially have 2 scuba dives, how much time must elapse between them?
What is the first aid for a diver with air embolism or decompression sickness?
The most common form of vertigo is caused by?
What is the no-decompression limit for a dive to 85' for your first dive of the day (in minutes)?
A diver goes to 20 feet and remains there for 35minutes. He returns to the surface and puts on another scuba and enters the water immediately. He descends to 75 feet. His bottom time is 32 minutes. After decompressing the appropriate length of time, he remains on the surface for 3 hours and 27 minutes. The next dive is to 112 feet for a bottom time of 13 minutes.
The repetitive group the diver is in after leaving the water from the 75' dive is?
The repetitive group the diver is in after the surface interval is?
The repetitive group the diver is in after all the diving is over is?
The remedy for air starvation caused by rapid swimming is to do what?
What is one of the most common errors for a diver to commit when compass-navigating?
What concerns are to be ignored when an unconscious diver is brought to the surface?
When you suspect nitrogen narcosis in either yourself or your buddy, the best course of action is to do what?
If you have trouble with any of the concepts related to the questions above ask about them in class. Also, please refer to the appropriate chapters of this textbook!
