This frightens me.
Let’s say the minimum passing score is 70%. A “lucky” person will correctly guess 1/3 of the unknown answers, so
Let X = the number of questions a “lucky” person must knowingly answer correctly and still get 70% (84 out of 120)
X + 1/3 (120 - X) = 84
2/3 X = 44
X = 66
Assuming a pass rate of 70%, 66 is the minimum number of questions we have to answer correctly if we’re “lucky.” Wouldn’t CFAI go out of its way to make it nearly impssible for someone to pass with a working knowledge of only 55% of the material? I think so.
So there are two tools I can think of at its disposal: raise the minimum passing score, or make the questions much more difficult than they have in the past. I tend to believe the latter, and I think we’re going to have a much tougher time this year finding 66 questions that we can nail off the bat.
I know, I should have been studying derivatives when I wrote this, but it’s been on my mind.
