How does 40/60/80 rule work?

CFA Level III
#1

Talking in context of L3 (not that I know how to apply is for L2,L1) Want to my approx. score. People seeming to have better score (looking at orientation of *) than me have failed, so really curious what could have been my score

#2

You estimate your score by supposing than you got 40% right in the <50% category, 60% in the 50%-70% category and 80% in the >70% category. You then multiply these scores by the relative weight of the topics.

Thanks for the info…I guess very narrowly passed with 63.61% …Phew!!!

#4

Well this method is only a very rough guess, knowing that <50% could mean near 0 as well as almost 50. Same for >70%, you could well lie by 100%… or not.
