I scored a 630 (40, 36) today. CATs taken after 11:00 AM EDT on August 29, 2012 are scored according to the new calibration. Older CAT scores are unaffected.
Recalibration applies to the scores received before 29th Aug , right?
Here's the original message from our website:
"CAT Recalibration – August 29, 2012
We have recalibrated our CAT scoring. CATs taken AFTER 11:00 AM EDT on August 29, 2012 are scored according to the new calibration. Older CAT scores are unaffected.
Why are scores being recalibrated?
We periodically recalibrate to have our CAT scores correspond to actual GMAT scores as closely as possible. In addition, the percentiles in our system now match the latest percentiles published by GMAC (earlier this month). These percentiles, especially on the quant side, are undergoing significant shifts.
What is the effect of the recalibration?
New MGMAT Quant subscores, on average, are lower by approximately 1 point.
New MGMAT Verbal subscores, on average, are lower by approximately 1-2 points.
New MGMAT Overall scores, on average, are lower by approximately 18 points.*
What does this mean for me?
When you compare older practice scores to practice scores generated after noon on August 29th, you should subtract 1-2 points from each old subscore and about 15-20 points from the old overall score, to get a rough sense of how you would have done under the new scoring.
We know that this is a significant recalibration, one that impacts your sense of your progress. We’re committed to making our CATs ever better over time.
*Note: An earlier measurement of the effect of the recalibration overestimated the average impact on subscores by 1-2 points and on overall scores by ~9 points"
