# 40-60-80? Not for the afternoon session!!

I understand the logic of using the 40-60-80 rule to estimate scores for the morning session. But I don’t understand it for the afternoon multiple-choice session. Think about it. There are 6 questions per 18-point item set. That means: <=50% signifies 0, 1, 2, or 3 correct answers. Equal weighting the likelihood of each, that gives you an estimated score of 25%. 51-70% signifies 4 correct answers, which is a score of 66.67%. >50% signifies 5 or 6 correct answers. Equal weighting the likelihood of each, that gives you a score of 91.67%. For 36-point item sets that means: <=50% signifies 0-6 correct answers. Estimated score of 25% (no different than 18-point sets). 51-70% signifies 7 or 8 correct answers. Estimated score of 62.5%. >50% signifies 9-12 correct answers. Estimated score of 87.5%. I thought I had done better in the afternoon session than my 40-60-80 scores suggested. When I recalculated using the 25-67-92/25-63-88 method, my afternoon scores looked more in line with my expectations.

did you just come out of nuke-proof bunker? I hope most of the people don’t use 40/60/80 approach for PM on L2 and L3. It is so outdated and L1

It is so outdated and L1 Yeah, i guess this is just a carry-over from L1. Still, if you read this forum, there are lots and lots of folks using 40-60-80 for afternoon score estimates. I did the same.
