Okay.. please tell me if I'm missing something here. Sorry if this gets confusing but this is a desperate attempt to calm my nerves re: the CPNE that I don't even have a date for!
The first time pass rate is 64%, second time is 64% and the third time is 59%. Lets say that there are only 100 people to take this test.
The first try, only 64 passed out of 100 (leaving 36 to retest)
The second try only has 36 people (because the rest passed the 1st time) Well, 64% pass of 36 people= 23 people passing. That now leaves 13 who didn't pass the 2nd time.
The thrid try comes around with 13 people left (that didn't pass the 1st or 2nd time). Out of the 13, 59% pass so that is 7 more people to pass the CPNE.
When you add up 64 (1st time pass) + 23 (2nd time pass) + 7 (3rd time pass) = 94 people who eventually pass out of the 100 that started. 94 out of 100.. seriously? Is my math or concept wrong?
I know there is more than 100 taking this exam.. even if it was 1000 people, that still makes 940 out of 1000 passing and so on...
Can anyone tell I am dwelling on this too much as I wait for my CPNE supplies to come in the mail??? Perhaps I need a few shots to relax:p

Your logic is incorrect and here is why:
"Lets say that there are only 100 people to take this test."
That is the breakdown in your logic: there are more than 100 people taking this test. It is not just that number is bigger and you are referring to a larger sample size for example n=892. If that were true and you applied your formula to this statement:
"Lets say that there are only 892 people to take this test."
Then you would still come out with the same percentage:
64% of 892=571 with 321 people remaining
64% of 321=205 with 116 people remaining
59% of 116=68
571+205+68=844 which is 95% of 892.
This seems to satisfy the "if n=true and n+1 =true, then its true"
So why is that wrong? Because your sample size is always changing. It is not static. Here is why:
The CPNE is offered at least on a monthly basis if you consider all the testing sites. Your reasoning might be correct if it were applied only to people who took the CPNE for the first time in November of 2008 (pick any month, but just that month). That is not the case though. Every month there is a new group of first time CPNE takers and each month 64 percent of these people will fail. So each month the number of people who will be taking the CPNE a second time will also be growing. You might have a group of second time CPNE takers this month (March, 2009) who are comprised of people who made their first CPNE attempt anytime ranging from years ago to those who failed just last month. In between then and now, that number of second (and third) time CPNE takers is ever changing. So A6fan is correct: each time your pool of people is going to be 100 (if you are working from percentages). None of this takes into account that not all people will decide to retake the CPNE a third or even a second time.
Does that make sense? Had to dust off the ol' brain for that one!

If you study and know the required information given to you by Excelsior, you should pass with ease. I did take the Excelsior workshop but did not learn anything that wasn't already in the study guide. This test is very basic and really comes down to using a grid and working well under stress. Everyone I passed with thought the actual requirements were super easy...but the supervision is a little rattling. The grid will save you--enough said! :)
Decompression fluid deficit r/t loss of abstract thought
aeb: loss of six people
the person will increase decompression fluid intake X6
the person will display signs of decreased cognitive thought
OK guys, we've had a few units of decompression fluid now let's take a fresh look at the math. If you start out with 100 people you will end up with 100.
Let's GO!
64 people passed the test the first time
23.04 passed the second time
7.6464 passed the third time
and that leaves 94.6864 people PASSING
now you have to add in the people who failed all three times which is 5.3136
if you add that to the people who passed
94.6864+5.3136= 100
Nothing that a little extra decompression fluid won't fix.
