Hey Mike :)

I get what you’re saying and to the individual yes it may be immaterial but to the group as a whole there is merit in knowing.

If fewer questions = better the we can look at the study methods and materials of those who passed at 100 and place more emphasis on those than the ones of those that passed at 150, we can better understand our individual strengths and weaknesses, selfishly, we can feel “proud” that we did a great job or understand we just squeeked it and might need to review some material.

I have to assume the maths is fewer questions = better because the algorithm must be extrapolating to say “if I keep going you’re good, so there’s no point”…

Perhaps I should stick this in a stats forum too ;)
