GARP says they take the top 5th quantile (i.e., whatever score cutoffs the top 5th “percentile”), then they take a ratio (e.g., 0.75) of that top score. I personally suspect the ratio (0.X of top 5%) is calibrated after the results are tabulated to approximate a ~50% pass result; or, best case, they use .75 of top 5% (e.g., if 0.75* top 5% only passes a small % due to high difficulty, I doubt they would keep it). But, either way, it’s really based on an (ex post) “grading on a curve” (no segmentation by section/topic, all questions weigh equally)...therefore: I do not think you can divine anything useful from the method. Unfortunately, it’s a waiting game. 来源:高顿财经 |
