Because getting as many AF Points = higher correlation of passing, duh! Doesn’t matter if those points come from asking quality questions / providing quality responses. All that matters is racking them up! lol
Yes, it corresponds to my estimate as well. I simply took several results of last year band 10 candidates and calculated median score from the distribution (e.g. 50-70% for quant means 3 or 4 correct answers, so the range is pretty narrow). It was ~62.5%.
Sounds like the 62.5% score you calculated from Band 10 results is a fail score for a Band 10. Surely scores for people who passed should be higher than that. If 62.5% was band 10 average score then MPS has to be higher?
