Here is my interpretation of what they mean when they say that the average pass mark is 76%:

Let's say the SOA sets a pass mark for all exams to be 75% then the number questions you need to get correct in order to pass is 23 for an exam with 0 pilots (0.7667), 22 for 1 (0.7586), 21 for 2 (0.75), 21 for 3 (0.7778), 20 for 4 (0.7692), and 19 for 5 (0.76). Assuming there are an equal number of exams with no pilots as there are with 1 pilot, etc., then the average pass mark that the SOA quotes is literally what it means i.e. 1/6 * (0.7667 + 0.7586 + ... + 0.76) = 0.7637 or 76%.

Also, suppose you had an exam with 5 pilots then the passing mark is 18.75 (0.75 * 25) and 10% of the passing mark on top of that is 20.625. Therefore if you got 19 or 20 questions correct then you would've gotten a 6. A 10 is equivalent to getting 27, 28, 29, or 30 questions correct on this exam.

The F bro, 76% means getting 19 correct out of 25. Plug 19 divided by 25 in your calculator and you will get 76%. Out of 30 questions, only 25 count, the 5 others are pilot questions.

I understand how pilots work, bro. If you answered 19 correctly and you had less than 5 pilots on your exam then you failed.

so how many questions out of 30 do we need to answer correctly in order to pass?

If you have an exam with 5 pilots you cannot get more than 25 correct. It may be impossible to get a 10.

Based on these estimates of 76%, you need 76% of the questions which count. No one knows for sure how many pilots there are. If you were sure there were 5 (and the 76% still applies) you would need at least 19, but you would need 19 of the ones which count. 23 of 30 right might not do it if you had pilots right and too many of the ones which count wrong.

If you have 5 pilots, how can you get more than 25 right? A 10 was impossible, regardless of how many pilots you had.

The way the exams are scored is all over the internets. 10% above the pass mark is a 7, 20% above is an 8, etc... A 10 was impossible on this exam.

I failed in April with a 3, and sitting again in November.

Also, I would guess both the increasing pass marks and pass rates have to do with the adapt and actuarial brew products, (neither of which I used for the April sitting), and the better study manuals that have improved significantly now that the exam has been around for a few years, not a higher mean IQ for the candidate pool.

i actually thought it wss neither, and just that the exam questions were easier this time. i used the same material for mlc and failed miserabl, but of course thats due largely to the syllabus change.

i am also surprised there is so much debate about the exam scores, there were a few very clear explanations on this thread and i dont thinl there are really other "interpretations"
