What is the number correct needed to pass? (NOV. 2005 FM exam)
or some reasonable estimation of what it could be from a reasonable source.

I would like to have some idea because i feel i had 16 correct, because I would like to have some Idea of what i have to do to pass FM, if I fail this sitting.

I would guess 17 or 18. I think it was 18 in the spring, so I don't see it being shifted too much.
