The text below is copied and pasted from the Instructor Manual. If you are any doubt about what you are being told by your instructor may I suggest that you conatct the training department at PADI (switchboard number 0117 3007234), they are most helpful, and answer my stupid questions all the time!
Stamina Assessment and Development
There are four exercises that evaluate
stamina and waterskills, each
rated by points. There is no passing
score for any single exercise, but
a combined score of 12 or more is
required prior to certification. In
addition, candidates must complete
all exercises prior to certi-
fication.
Candidates who fall short of a
combined score of 12 may be given
time to practice and develop their
abilities while continuing in other
areas of the course.
