Sure, but there’s certainly many scores we haven’t seen that leave it quite uncertain (in fact, the scores using the 40/60/80 method don’t really mean anything unless those assumptions are true or close to the truth-- I haven’t seen anyone substantiate this assumption)
It’s difficult because the score bands are so wide (and there’s one for each topic), we don’t have exact scores, and we’re dealing with a (likely) biased sample
Nothing is wrong with being over-excited. I don’t recall saying anything about that, specifically.
Well, if a candidate pass, I think he did good on the entire exam. CFAI apparently does not use 80% as a “good” since the pragmatic MPS is around 65%. Maybe when you get a final score near to the MPS would be labeled as an “enough”, but we will never know anyway.
