I think 100% is possible… but out of 25000 level 3 test takers maybe only the top 0.01% so maybe 25 candidates in the world get it with a bit of luck… I think it’s actually easier to get 100% in AM for the top candidates but in PM there are 2-3 questions that are coin flips at best.
anything above 80% is probably top 10%… and it’s likely just as hard to get below 40%
I’m terrible with statistics but the distribution of score must be leptokeuric? very tight between 55-65%… and CFAI sets the MPS in there to inflict max pain…
With 25000 candidates, the 99th percentile would be around 90-92 (after throwing out the unfair questions), so think 145/160 (assuming 20 mins get thrown out).
We see a lot of comments about actual test being easier than mock. We also know that unfair questions are thrown out. So i guess 90% for the Top1% candidates is not unlikely.
